SEDIT and S/REXX

Mainframe-caliber tools for UNIX

Offered by

Treehouse Software, Inc.

sedit
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
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
sedit mainframe familiarity
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

editing extensions
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
unix specific extensions
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
unix specific extensions1
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

#! /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

execio support
EXECIO Support
  • Facilitates porting from mainframe to UNIX
  • Supports I/O to files and printers
  • All CMS EXECIO options available
unlimited program size and complexity
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
unix specific extensions2
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)
gui extensions
GUI Extensions
  • Display OpenLook or MOTIF dialog boxes, with input fields, toggles, and buttons
enhanced trace mode
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)

enhanced trace mode1
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”

enhanced trace mode2
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”
