Question about ISPF start service

Postby marshall25 » Wed May 08, 2013 8:35 am

hi all,

i just read the ISPF start service for ISPEXEC SELECT PGM(ISPSTRT) PARM(some_dialog),

i tested,
ISPEXEC SELECT PGM(ISPSTRT) PARM(3;4)
it worked to goto 3.4 in new screen.

i don't know what kind of 'some_dialog' can be used in PARM, if i want to goto 3.4 and enter, how can i write the dialog?

The program ISPSTRT creates a new (splitted) screen similar to the SPLIT command. The parameter can be used to issue any command on this newly created screen and simulate the ENTER key. So you are able to start any application in a new screen programmatically. ISPSTRT is not about "writing a dialog" but gives you the starting point for invoking a program, a command, or select a panel option.
There are 10 types of people in the world: Those who understand binary, and those who don't.

Can you elaborate on what you want to do? And where you want to do it?

Totally unclear and not sure why you woukd want to do this anyway.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

The DSLIST command does exactly what you are trying to do.

Examine the ISP command table in ISPF option 3.9 and study the definition of DSLIST. You want to replicate the exact same SELECT statement into your rexx program. Except, replace &ZPARM with the dataset prefix of your choosing.

I did something similar, but of course, I did not follow my own advice. I actually issued the DSLIST command:

/*-------------------------------------------------------------------*/
/* view DSLIST of the superc files                                   */
/*-------------------------------------------------------------------*/
dslist_supr:                                                           
ispfcmd = "DSLIST  '"|| superc_dsn || "'"                                 
"DISPLAY PANEL(aaaaaaa) COMMAND(ISPFCMD)"                             
return
