Reply with quote

Hi everybody,

in our homegrown software configuration interface I want to offer a line command which starts a VIEW on a dataset in a newly splitted screen. I already know how to split the screen and start a VIEW. But to present a message if the user has already reached the limit of screen splits (in our installation it's 8) I need to know how many screens are currently open.
I've studied the manuals but didn't found any ISPF variable containing the total of current screens.
Any idea on this?

I usually use LIST and then hit PF9.

I do have an example of the REXX code to show this, but can't access it at work.

Will try to find it and post later when I get back home

The ISPF variable ZSCRCUR gives the number of screens currently open and ZSCRMAX gives the max number of screens allowed.

Hope this helps.

Take a look at option 7. whatever - that's how I think I found the required variable name.

Unfortunately no TSO access with this contract icon_cry.gif

Here is a sample that I tested:

Code:
/* REXX */                         
                                   
   "ISPEXEC VGET     (ZSCRMAX )   "
   "ISPEXEC VGET     (ZSCRCUR )   "
                                   
   SAY 'ZSCRMAX     = ' ZSCRMAX   
   SAY 'ZSCRCUR     = ' ZSCRCUR

Thanks to mistah kurtz,
I missed the description of this variable as I searched for the term "split".
ZSCRCUR did the trick.

You can use SWAPBAR ON in the Command line and can view in which screen you are into, and can move to the required screen by just double clicking it.
