First Edition: November 1986 FOREWORD INTRODUCTION TO FLEXOSTM FlexOS is an advanced multitasking operating system for microcomputers. What does that mean for you? In our daily work we rarely do only one thing at a time, finishing one task and putting it away before picking up the next task. Usually we're doing several things at once: preparing reports, answering the telephone, jotting down notes, and calculating columns of figures. We certainly don't want our computers to be limited to doing only one task at a time. But that is exactly the limitation of most microcomputer systems. For example, if you are preparing a report with a word processing program and need some figures from your spreadsheet program, you would have to close and save your report file, exit the word processor, start the spreadsheet program, retrieve the figures, exit the spreadsheet program, start the word processor again ... you get the idea. With multitasking built into your operating system, you can keep several programs (processes) running simultaneously, and you can hop back and forth between them as you need to. The advantages are clear: faster, more efficient work and none of the frustration of constantly stopping and starting each program. That's what FlexOS will do for you. iii WHAT THIS GUIDE CONTAINS The FlexOS User's Guide provides a full description of the FlexOS operating system, including the following: • the command line and some basic FlexOS commands • directories and subdirectories • wildcard and logical names • windows • input/output redirection • DR EDIX™*, the FlexOS text editor • batch processing • how FlexOS handles errors Section 7 is a reference summary of FlexOS commands. Appendix A describes the role of the system manager, the person who sets up and manages a FlexOS system with more than one user. ON-LINE ERROR MESSAGES FlexOS displays an on-line error message if an error occurs while you are working with the operating system. FlexOS lets you set your own "help level," the amount of information displayed in the error message. If you are a beginning user, you can set a help level so that FlexOS describes each error in detail. At this level FlexOS usually suggests a solution for the error encountered. You can also refer to Appendix B for information on common error situations. *Edix™ is a trademark of Emerging Technology Consultants, Inc. IV If you are an experienced user, you can set your help level so that FlexOS displays a briefer message. Setting the help level is described under the DEFINE command in Section 7. OTHER BOOKS ON FLEXOS The User's Guide is one of several Digital Research... books about FlexOS. The other books in this set include: • FlexOS Programmer's Guide. This book identifies the C­ based software tools and techniques used to write programs that can run on FlexOS. • FlexOS System Guide. This book describes the architecture of the microchip processor that supports FlexOS. Digital Research also publishes microprocessor-specific supplements and programmer's utilities guides to FlexOS. TERMS AND CONVENTIONS Hardware This guide uses the terms "diskette," "hard disk," and "disk" in the following manner: diskette The 3 1/2-inch, 5 1/4-inch or a-inch magnetic disks that can be inserted into and removed from your microcomputer. Your system must have at least one diskette drive. hard disk An internal or external fixed magnetic disk. Your system might not have a hard disk. v disk The term used when information applies to both diskettes and hard disks. For example, "disk drive" means either a diskette drive or a hard disk drive. User Input and FlexOS Output This guide uses boldface and regular type to distinguish between user input and system output, as in the following example. The system prompt (A» is in regular type. Following that is the user input in boldface type. The next line shows what the system returns to the user.. This is also show,n in the regular typeface.

  • TRSDOS 6.2 to LS-DOS 6.3.0 Manual Update

    TRSDOS 6.2 to LS-DOS 6.3.0 Manual Update

    LS-DOSÔ 6.3 UPDATE FOR TRSDOSâ 6.2.X The LS-DOS 6.3 release is an upgrade for the TRSDOS 6.2 operating system. Several important changes have been made to extend and enhance the operating system and its utilities. The date ranging has been expanded to accept dates through the year 1999. Files will now carry a modification time as well as a date. The DATECONV/CMD program is provided to translate version 6.2 or earlier disks to the 6.3 style dating. The user password has been eliminated from the system. The owner password still remains. The library command ID was added to display a customer service number. Several enhancements have been made to BASIC. The new DISKCOPY/CMD program will duplicate 5" double density floppy disks. Because the LS-DOS 6.3 update is a series of enhancements to TRSDOS 6.2, the primary documentation remains the 6.2 manual and Technical Reference manual. If you have a version of TRSDOS earlier than 6.2, you can obtain the manuals from Radio Shack under the catalog numbers 26-0316 (TRSDOS Version 6 [6.2 DOS manual and disk]), 26-2110 (Model 4/4D [6.2] Technical Reference Manual), or 26-1117 (6.2 DOS manual only). This documentation should be treated as an addendum to the TRSDOS 6.2 information. LS-DOS 6.3 installation instructions Before performing the upgrade, it is recommended that you make several backup copies of the 6.3 master disk. The simplest way to do this is to boot your system using the 6.3 diskette, insert a blank diskette to receive the copy in drive 1, and type the command: DISKCOPY :0 :1 When the copy finishes, you can insert another destination diskette and make another copy.

    Older Operating Systems Class Notes # 10 Batch Files (Part 2) October 23, 2003 IF Condition When a given condition is true, the statement is executed. When the given condition is false, the statement is not executed. Figure one illustrates the flow chart for the IF condition. IF entry point No Decision Yes Statement (perform some action) IF exit point Figure 1: IF condition flow chart The IF condition tests the following three conditions: • The ERRORLEVEL of a program • Whether a string is equal to another string • Whether a file exists Using IF to test ERRORLEVEL The syntax for testing the ERRORLEVEL is: IF ERRORLEVEL number command This form of the IF condition determines whether the value of ERRORLEVEL is greater than or equal to a number specified in the number parameter. IF NOT ERRORLEVEL number command This form of the IF condition determines whether the value of ERRORLEVEL is not greater than or equal to a number specified in the number parameter. 1 If the specified condition is true, DOS executes the command specified in the command parameter. Otherwise, DOS skips to the next line in the batch file without executing the command in the command parameter. The only DOS commands that leave an ERRORLEVEL (exit) code are: BACKUP, DISKCOMP, DISKCOPY, FORMAT, GRAFTABL, KEYB, REPLACE, RESTORE, and XCOPY. Many other programs generate exit codes, however. For example, table one contains codes that are generated by the DISKCOPY command. Table one: DISKCOPY codes Code Description 0 The operation was successful. 1 A read/write error occurred that did not terminate the disk copy operation.
