  1. SEDIT and S/REXX Mainframe-caliber tools for UNIX Offered by Treehouse Software, Inc.

  2. SEDIT • UNIX text editor • Emulates mainframe XEDIT and ISPF/PDF editors under UNIX • Goes beyond XEDIT and ISPF/PDF • Takes advantage of the UNIX environment • Includes Directory Tree Utility • Provides FLIST-like functionality

  3. Why SEDIT? • Mainframe users unfamiliar (and unhappy) with UNIX editors such as "vi" and "emacs" • UNIX editors may lack power and flexibility seen on the mainframe • Cost of training former mainframe users to operate UNIX editors can be prohibitive • Training periods can result in project delays

  4. SEDIT: Mainframe Familiarity • Supports the familiar keystrokes and commands used on the mainframe: • Insert, Copy, Delete, Split, Join, Get, etc. • Function keys, split-screen mode, and more • Character-based interface closely resembles mainframe screens • FLIST-like utility for UNIX directory navigation

  5. Character Mode Interface UNIX path and name of file being edited Editing area Command line Function key settings

  6. Optional GUI Interface CompilerSupport Buttons(can be customized) Command line Function key settings

  7. FLIST-like Utility Modificationdate/time UNIX command entry area UNIX permissions file, directory names file types File sizes directories specified in the UNIX "PATH" environment variable Function key settings

  8. Editing Extensions • Cut/Copy/Paste between files • Unlimited Undo • Recall of previously-entered commands • Complete on-line help system • Spelling checker • Automatic save option • Programmable function keys, allowing keyboard short-cuts to be created • User-customized menus and buttons • "Search and replace" for FORTRAN and C variables

  9. UNIX-Specific Extensions • Allows use of abbreviated path names • "benefits.c" versus "usr/fred/payroll/benefits.c" • Supports use of the mouse • Supports OpenLook, and Motif GUIs • Supports compilers, and can automatically position the cursor on lines of code which generated compiler errors • Provides a scrollable interface to the UNIX "man" command

  10. UNIX-Specific Extensions • Includes an external macro interface, allowing the use of any language as a macro language • Interacts with CenterLine Software's CodeCenter • "Listens" on a socket for commands sent by other UNIX applications • Displays files in WYSIWYG format • Offers graphical Directory Tree Utility

  11. Directory Tree Utility

  12. SEDIT Summary • Emulates mainframe XEDIT and ISPF/PDF editors under UNIX • Character and GUI modes • Powerful editing extensions • UNIX-specific extensions • Flexible, customizable

  13. S/REXX Overview • REXX implementation for UNIX • Supports Cowlishaw REXX Level 4.0 • No limitations on program size or complexity • UNIX-specific functionality • GUI Extensions • Enhanced Trace Mode • Optional S/REXX Debugger product

  14. Mainframe Familiarity #! /home/xed/srexx say 'Enter a positive number' pull rep . if test_nump(rep) then say 'Valid number' else say 'Invalid number' exit test_nump: if datatype(rep) = 'NUM' & rep > 0 then return 1 else return 0

  15. EXECIO Support • Facilitates porting from mainframe to UNIX • Supports I/O to files and printers • All CMS EXECIO options available

  16. Unlimited Program Size and Complexity • No limitations on: • Procedure size • Expression complexity • Number of nested parentheses • Number and content of variables • Recursive function depth • Argument number and size • S/REXX programs can be as large and as complex as your hardware and UNIX operating system dictates

  17. UNIX-Specific Extensions • Permits C programs to execute S/REXX programs • Executes UNIX commands and uses the output in S/REXX programs • Supports "Choices," a menu replacement appropriate for use in dialog boxes • Includes C program interface • Supports dynamic loading of external procedures • UNIX file manipulation functions (e.g., "RM" to remove a UNIX file)

  18. GUI Extensions • Display OpenLook or MOTIF dialog boxes, with input fields, toggles, and buttons

  19. Enhanced Trace Mode • Consider these REXX commands: trace I a = 2 str = “This is a” id = 1 tab.a = substr(str||” string”, id+1, 2)

  20. Enhanced Trace Mode • Mainframe REXX trace output: 5 *-* a = 2 >L> “2” 6 *-* str = “This is a” >L> “This is a” 7 *-* id = 1 >L> “1” 8 *-* tab.a = substr(str || “ string”,id + 1,2) >V> “This is a” >L> “ string” >O> “This is a string” >V> “1” >L> “1” >O> “2” >L> “2” >F> “hi”

  21. Enhanced Trace Mode • S/REXX trace output: 5 *-* a = 2 >>> A <-- “2” 6 *-* str = “This is a” >>> STR <-- “This is a” 7 *-* id = 1 >>> ID <-- “1” 8 *-* tab.a = substr(str||“ string”,id+1, 2) >C> TAB.A --> “TAB.2” >V> STR --> “This is a” >O> “This is a” || “ string” --> “This is a string” >V> ID --> “1” >O> “1” + “1” --> “2” >F> SUBSTR() --> “hi” >>> TAB.2 <-- “hi”

  22. Optional S/REXX Debugger • Separately-priced product • Graphical debugging environment for S/REXX • Step through the execution of S/REXX programs • Find and fix bugs while in the debugger • Set and remove breakpoints

  23. S/REXX Debugger Breakpoint Column Source area Command area I/O area

  24. S/REXX Summary • REXX for UNIX • Mainframe compatibility • UNIX-specific extensions • GUI support • Enhanced Trace Mode • Optional S/REXX Debugger product • Integrated with SEDIT

  25. Operating System Support • SEDIT, S/REXX, and the S/REXX Debugger support: • IBM's AIX • Hewlett Packard's HP/UX • Sun Microsystems' SunOS and Solaris • SiliconGraphics' IRIX • Santa Cruz Operation's (SCO) UNIX • DEC UNIX • PC Unixware • Linux • Windows NT and Windows 95 • Other popular UNIX operating systems

  26. Conclusion • SEDIT, S/REXX, and the S/REXX Debugger are mainframe-caliber tools for UNIX • Mainframe familiarity with UNIX-specific functionality • Optional GUI features • Support most popular UNIX operating systems • Attractively priced, with quantity discounts available
