1 1 SED/SRX-7/01 SEDIT and S/REXX Mainframe-caliber tools for UNIX Offered by Treehouse Software, Inc.

2 2 SED/SRX-7/01 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 3 SED/SRX-7/01 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 4 SED/SRX-7/01 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 5 SED/SRX-7/01 Character Mode Interface UNIX path and name of file being edited Command line Function key settings Editing area

6 6 SED/SRX-7/01 Optional GUI Interface Buttons (can be customized) Compiler Support Function key settings Command line

7 7 SED/SRX-7/01 FLIST-like Utility UNIX permissions file, directory names file types directories specified in the UNIX "PATH" environment variable Function key settings UNIX command entry area File sizes Modification date/time

8 8 SED/SRX-7/01 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 9 SED/SRX-7/01 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 10 SED/SRX-7/01 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 11 SED/SRX-7/01 Directory Tree Utility

12 12 SED/SRX-7/01 SEDIT Summary Emulates mainframe XEDIT and ISPF/PDF editors under UNIX Character and GUI modes Powerful editing extensions UNIX-specific extensions Flexible, customizable

13 13 SED/SRX-7/01 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 14 SED/SRX-7/01 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 15 SED/SRX-7/01 EXECIO Support Facilitates porting from mainframe to UNIX Supports I/O to files and printers All CMS EXECIO options available

16 16 SED/SRX-7/01 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 17 SED/SRX-7/01 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 18 SED/SRX-7/01 GUI Extensions Display OpenLook or MOTIF dialog boxes, with input fields, toggles, and buttons

19 19 SED/SRX-7/01 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 20 SED/SRX-7/01 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 21 SED/SRX-7/01 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 22 SED/SRX-7/01 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 23 SED/SRX-7/01 S/REXX Debugger Source area I/O area Command area Breakpoint Column

24 24 SED/SRX-7/01 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 25 SED/SRX-7/01 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 26 SED/SRX-7/01 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
