SEDIT and S/REXXSEDIT and S/REXXMainframe-caliber tools for UNIX

Offered byTreehouse Software, Inc.

2SED/SRX-7/01

SEDITSEDIT

• 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

3SED/SRX-7/01

Why SEDIT?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

4SED/SRX-7/01

SEDIT: Mainframe FamiliaritySEDIT: 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

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

15SED/SRX-7/01

EXECIO SupportEXECIO Support

• Facilitates porting from mainframe to UNIX

• Supports I/O to files and printers

• All CMS EXECIO options available

16SED/SRX-7/01

Unlimited Unlimited Program Size and ComplexityProgram 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

17SED/SRX-7/01

UNIX-Specific ExtensionsUNIX-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)

18SED/SRX-7/01

GUI ExtensionsGUI Extensions• Display OpenLook or MOTIF dialog boxes, with

input fields, toggles, and buttons

19SED/SRX-7/01

Enhanced Trace ModeEnhanced Trace Mode

• Consider these REXX commands:

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

20SED/SRX-7/01

Enhanced Trace ModeEnhanced 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”

21SED/SRX-7/01

Enhanced Trace ModeEnhanced 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”
