1 SEDIT & S/REXX

SEDIT and S/REXXMainframe-caliber tools for UNIX

Offered byTreehouse Software, Inc.

2 SEDIT & S/REXX

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 SEDIT & S/REXX

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 & S/REXX

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

8 SEDIT & S/REXX

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 SEDIT & S/REXX

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 SEDIT & S/REXX

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

SEDIT Summary

• Emulates mainframe XEDIT and ISPF/PDF editors under UNIX

• Character and GUI modes• Powerful editing extensions• UNIX-specific extensions• Flexible, customizable

13 SEDIT & S/REXX

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 SEDIT & S/REXX

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 SEDIT & S/REXX

EXECIO Support

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

16 SEDIT & S/REXX

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 SEDIT & S/REXX

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 SEDIT & S/REXX

GUI Extensions• Display OpenLook or MOTIF dialog boxes,

with input fields, toggles, and buttons

19 SEDIT & S/REXX

Enhanced Trace Mode

• Consider these REXX commands:

trace Ia = 2str = “This is a”id = 1tab.a = substr(str||” string”, id+1, 2)

20 SEDIT & S/REXX

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 SEDIT & S/REXX

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 SEDIT & S/REXX
