hi,all, I'm a new TSO$ISPF student,i found there are some fields not initialized or gaven value in panel, but if i issued the panel, the fields will have the value,my question is how can i find where the field's value comes from? is it from program or higher level which displayed the panel? thanks,

Remember that every named field in your panel corresponds to a variable in the driver code.

So, suppose your panel has a field named FOO. If a Rexx driver script contains
foo = "BAR"
address ispexec "DISPLAY PANEL(P1)"

then the panel will be displayed with "BAR" in field FOO.

hi Akatsukamin,i got it, but another confuse was raised in my mind, u used 'display panel' in the example, how about to use 'select panel' instead? i just went through the ISPF panel service, but still not clear about 'display panel' and 'select panel', is that different 'select panel' uses 'CMD' to execute program in proc?
