The SGID.procedure involves a number of steps:contact between the facilitator and instructor; classroomintervention to ascertain student opinions; a feedback session between facilitator and instructor; instructor. review of the SGID with the class;and ,a follow-up session between the facilitator and instructor.Following the development of the SGID process, handouts andvideotapes were produced to explain the procedure and the SGID technique was demonstrated in over 130 classes

Bischoff Iowa State University Follow this and additional works at: http://lib.dr.iastate.edu/cs_techreports Part of the Programming Languages and Compilers Commons Recommended Citation Bischoff, Kurt M., "User Manual for Ox: An Attribute-Grammar Compiling System based on Yacc, Lex, and C" (1992). Computer Science Technical Reports. 21. http://lib.dr.iastate.edu/cs_techreports/21 This Article is brought to you for free and open access by the Computer Science at Iowa State University Digital Repository. It has been accepted for inclusion in Computer Science Technical Reports by an authorized administrator of Iowa State University Digital Repository. For more information, please contact [email protected]. User Manual for Ox: An Attribute-Grammar Compiling System based on Yacc, Lex, and C Abstract Ox generalizes the function of Yacc in the way that attribute grammars generalize context-free grammars. Ordinary Yacc and Lex specifications may be augmented with definitions of synthesized and inherited attributes written in C syntax. From these specifications, Ox generates a program that builds and decorates attributed parse trees. Ox accepts a most general class of attribute grammars. The user may specify postdecoration traversals for easy ordering of side effects such as code generation. Ox handles the tedious and error-prone details of writing code for parse-tree management, so its use eases problems of security and maintainability associated with that aspect of translator development. The translators generated by Ox use internal memory management that is often much faster than the common technique of calling malloc once for each parse-tree node.

What is the Visual Text Editor (vi)? The Visual Test Editor, more commonly known as the vi text editor, is a standard “visual” (full screen) editor available for test editing in UNIX. It is a combination of the capabilities of the UNIX ed and ex text editors. It has specific modes for text insertion and deletion as well as command entering. Type view on the command line of the UNIX shell terminal to enter the read- only mode of vi. To switch between the line editor, ex, mode and the full screen wrapmargin vi mode: • To enter the ex mode from the vi mode, type Q • To enter the vi mode from the ex mode, type vi When vi is entered on the command line, you enter vi’s command (entering) mode. Positioning and editing commands can be entered to perform functions in this mode whilst advanced editing commands can be entered following a colon (:) that places you at the bottom of the file. To enter text insertion mode, a vi text insertion command i, o, or a is typed so that text will no longer be interpreted as positioning or editing commands in this mode.
