The line reference numbers start arbitrarily at 1438 and have blocks o f numbers missing. Their Palo Alto Tiny BASIC, version 1, was originally published main relevance is for cross referencing the symbols in Dr. Dobb's Journal of Computer Calisthenics and and for keeping the lines o f code in order. —Ed. Orthodontia, Vol. 1 No. 5, May, 1976. Version 1.0 of PATB was published in Dr. Dobb's ARITHMETIC AND COMPARE OPERATORS Journal (Vol. 1, #5). Version 2.0 was published in Interface Age (Vol. 2, #1). The version presented / divide.

In Ver if not true. sion 2.0, there is one known bug: ABS(0) gives an error. These bugs are fixed in Version 3.0. EXPRESSIONS
THE LANGUAGE Expressions are formed with numbers, variables, and functions with arithmetic and compare opera NUMBERS tors between them. + and - signs can also be used at the beginning of an expression. The value of an All numbers are integers and must be between expression is evaluated from left to right, except -32767 and 32767. that * and / are always done first, + and - next, and compare operators the last. Parentheses can VARIABLES also be used to alter the order of evaluation.
There are 26 variables denoted by letters A STATEMENTS through Z. There is also a single array @(l). The dimension of this array (i.e., the range of values of A Tiny BASIC statement must consist of a state the index I) is set automatically to make use of all ment number between 1 and 32767 followed by the memory space that is left unused by the pro one or more commands. Commands in the same gram (i.e., 0 through SIZE/2, see SIZE function statement are separated by a semi-colon. below). GOTO, STOP, and RETURN commands must be the last command in any given statement. FUNCTIONS PROGRAM Without extension, there are only 3 functions. More functions can be added as extensions. A Tiny BASIC program consists of one or more ABS(X) gives the absolute value of X. statements. When a direct command RUN is RND(X) gives a random number between 1 issued, the statement with the lowest statement and X (inclusive). number is executed first, then the one with the SIZE gives the number of bytes left unused next lowest statement number, etc. However, the by the program. GOTO, GOSUB, STOP, and RETURN commands can alter this normal sequence. Within the state The first command w ill print the value of the ex ment, execution of the commands is from left to pression A * 3 + 1 (e.g., 307), the string of charac right. The IF command can cause the execution of ters ABC"123, and the string #'!@%, and then all commands to its right in the same statement to start a new line. Note that either single or double be skipped. quotes can be used to quote strings, but pairs must be matched. The second command will produce COMMANDS the same output as the first, except that it will not start a new line after the last item is printed. This Tiny BASIC commands (un-extended) are listed enables the program to continue printing on the below with examples. More commands can be same line with another PRINT command. added as extensions. Remember that commands can be concatenated with semi-colons. In order to Numerical values are printed with leading blanks store the statement, you must also have a state so that they take 8 spaces each. This field width ment number in front of the commands. The state can be changed by a # sign followed by a number ment number and the concatenation are not indicating the new width. The new width w ill be shown in the examples. effective until the end of this PRINT command unless changed again by # n. Note that no trailing REM OR REMARK COMMAND space is printed. Extra spaces can be generated by repeated commas. REM causes the interpreter to ignore the rest of the line. This allows the programmer to put re PRINT A, #3, B,„ C + 1, marks in the program. This w ill print the value of A in 8 spaces, the value of B in 3 spaces (more if B > 999 or B < -99), two LET COMMAND extra spaces, and the value of C + 1 in 3 spaces (more if C > 998 or C < -100). LET A=234 - 5 * 6, A=A/2, X=A-100, @(X + 9)=A - 1 PRINT I L, I K, I I, w ill set the variable A to the value of the expres This command w ill print the control characters FF sion 234 - 5 * 6 (i.e., 204), set the variable A (control L), VT (control K), and HT (control I). (again) to the value of the expression A/2 (i.e., Control characters can also appear inside quotes, 102), set the variable X to the value of the expres but the method used here makes them visible in sion A - 100 (i.e., 2), and then set the variable the program listing. @(11) to 101 (where 11 is the value of the expres sion X + 9 and 101 is the value of the expression A - 1). INPUT COMMAND LET U=A # B, V=(A > B) * X + (A < B) * Y INPUT A, B w ill set the variable U to either 1 or 0 depending on whether A is not equal to or is equal to B, re When this command is executed, Tiny BASIC will spectively; and set the variable V to either X, Y or print A, a space, and wait to read in an expression 0 depending on whether A is greater than, less from the keyboard. The variable A w ill be set to than, or equal to B, respectively. the value of the input expression. Then B is print ed with a space and variable B is set to the value of PRINT COMMAND the next expression read from the keyboard.
PRINT A *3+ 1, 'ABC"123', INPUT 'WHAT IS YOUR WEIGHT?'A, "YOUR PRINT A * 3 + 1, 'ABC''123', HEIGHT?"B This is the same as the command above, except the GOSUB AND RETURN COMMANDS prompt: A is replaced by: WHAT IS YOUR WEIGHT?, and the prompt: B is replaced by: GOSUB command is different from GOTO com YOUR HEIGHT?. Again, both single and double mand in that: a) the current statement number quotes can be used as long as they are matched. and position w ithin the statement is remembered; and b) a semi-colon and other commands can fo l In both of the above examples, if the input (at run low GOSUB in the same statement. time) from the keyboard is not a valid expression. Tiny BASIC w ill reprint the prompt and wait agair GOSUB 120 until a valid expression is entered. One may also choose to reprint only part of the prompt, e.g.: will cause the execution to jump to statement 120.
INPUT "WHAT IS", "YOUR WEIGHT?"A, GOSUB A * 10+ B "YOUR HEIGHT?"B will cause the execution to jump to the statement In this case, WHAT IS YOUR WEIGHT? will be as computed from the given expression A * 10 + B. asked the first time; while only the part of YOUR WEIGHT? will be repeated if an invalid input is RETURN given. A RETURN command must be the last command in a statement followed by a CR. When a RETURN command is encountered, execution will IF COMMAND jump back to the command following the most recent GOSUB command. IF A ( B LET X=3; PRINT'THIS STRING' GOSUB can be nested. The depth of the nest is will test the value of the expression A < B. If it is limited only by the stack space. not zero (i.e., if it is true), the commands in the rest of this statement w ill be executed. If the value FOR AND NEXT COMMANDS of the expression is zero (i.e., if it is not true), the rest of this statement w ill be skipped and execu FOR X=A + 1 TO 3 * B STEP C - 1 tion continues at the next statement. Note that the word 'THEN' is not used. The variable X is set to the value of the expression A + 1. The values of the expressions (not the ex pressions themselves) 3 * B and C - 1 are remem bered. The name of the variable X, the statement GOTO COMMAND number and the position of this command within the statement are also remembered. Execution GOTO 120 then continues the normal sequence until a NEXT command is encountered. w ill jump to statement 120 and proceed from that statement on. Note that GOTO command cannot The STEP can be positive, negative or even zero. be followed by a semi-colon and other commands. The word STEP and the expression following it It must be ended with a CR. can be omitted if the desired STEP is +1.
GOTO A * 10 + B NEXT X will jump to a statement number as computed The name of the variable (X) is checked with that from the value of the expression and proceed from of the most recent FOR command. If they do not that point on. agree, that FOR is terminated and the next recent FOR is checked, etc. When a match is found, this LIST 120 variable w ill be set to its current value plus the value of the STEP expression saved by the FOR will print out all the statements starting at state command. The updated value is then compared ment 120. with the value of the TO expression also saved by the FOR command. If this is within the lim it, exe LIST 120,5 cution will jump back to the command following the FOR command. If this is outside the lim it, will print out 5 lines starting at statement 120. execution continues following the NEXT com mand itself. NEW

If a new FOR com mand with the same control variable as that of an STOPPING THE EXECUTION old FOR command is encountered, the old FOR will be terminated automatically. The execution of program or listing of program can be stopped by typing Control-C. STOP COMMAND ABBREVIATION AND BLANKS STOP You may use blanks freely, except that numbers, This command stops the execution of the program command key words, and function names can not and returns control to direct commands from the have embedded blanks. input device. It can appear many times in a pro gram but must be the last command in any given You can truncate all command key words and statement; i.e., it cannot be followed by semi function names with a period. 'P.', 'PR.', 'PRI.', colon and other commands. and 'PRIN.' all stand for 'PRINT'. Also the word LET in LET command can be omitted. The 'shortest' abbreviation for all key words are as DIRECT COMMANDS follows:
As defined earlier, a statement consists of a state A.=ABS F.=FOR ment number followed by commands. If the state GOS.=GOSUB G.=GOTO ment number is missing, or if it is 0, the com IF=IF IN.= INPUT mands w ill be executed (instead of saved) after =LIST N.=NEW you have typed the CR. A ll commands described =NEXT P.=PRINT above can be used as direct commands. There are REM=REMARK R=RETURN three more commands that can be used as direct R.=RND R.=RUN commands but not as part of a statement: S.=SIZE S.=STEP S.=STOP TO=TO RUN Implied = LET
will start execution of the program starting at the lowest statement number. ERROR REPORT
LIST There are only three error conditions in Tiny BASIC. The statement that contains an error is w ill print out all statements in ascending numerical printed out with a question mark inserted at the order. point where the error is detected. (1) WHAT? means it does not understand you. HOW? Example: 380 GOTO 412? where statement 412 does not exist
WHAT? (3) SORRY means it understands you and 210 P?TINT "THIS" knows how to do it but there is not enough where PRINT is mistyped memory to do it.
ERROR CORRECTIONS WHAT? 260 LET A=(B + 3?, C=3 + 4 If you notice an error in typing before you hit the where a close parenthesis is missing CR, you can delete the last character by the BS (Control H) key.
(2) HOW? means it understands you but does To correct a statement, you can retype the state not know how to do it. ment number with the correct commands. Tiny BASIC w ill replace the old statement with the new one. HOW? 310 LET A=B * C? + 2 To delete a statement, type the statement number where B * C is larger than 32767 followed immediately by a CR. ■ ********************* I************ 4*********************************** * * T B I * TINY BASIC INTERPRETER * VERSION 3.0 * FOR aoeo SYSTEM * LI-CHtN WANG * 26 APRIL. 1977 * v********************************************************************* * * * * * MEMORY USAGE * * * * * 0080-01FF ARfc FOR VARIABLES.
