Introduce self and Treehouse Software, paraphrase information on this slide.
PLEASE BE AWARE THAT THESE SPEAKER NOTES ARE INTENDED FOR THE INTERNAL USE OF TSI AND ITS AFFILIATES ONLY, AND ARE NOT INTENDED FOR DISTRIBUTION TO CUSTOMERS, POTENTIAL CUSTOMERS, OR OTHERS!
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
Buttons (can be customized)
Compiler Support
Command line
Function key settings

7. FLIST-like Utility Modification date/time UNIX command entry area
UNIX permissions
UNIX command entry area
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”
>O> “2”
>F> “hi”

21. Enhanced Trace Mode S/REXX trace output: 5 *-* 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
