Hi,

I have three panels say A and B and C. All are selection panels. B and C panels are called from panel A by ZSEL command. B and C panels both call same rexx program say REXXPROG.

Panel A:
Code:
)ATTR DEFAULT(%+_)                                   
      $ TYPE(TEXT) INTENS(LOW) SKIP(ON) COLOR(GREEN) 
      ! TYPE(INPUT) INTENS(LOW) PAD(_) color(white)   
)BODY  Expand(\\)                                     
+-\-\- Code Generator -\-\-                           
+                                                     
%OPTIONS ===>!opt                                   
+                                                     
+                                                     
+   Select below options to continue..               
                                                     
+  %1.$ Call Panel B.                             
+                                                     
+  %2.$ Call Panel C.                             
)PROC                                                 
    &ZSEL=TRANS(TRUNC(&opt,'.')                     
             1,'panel(B)'                           
             2,'panel(C)'                         
             ' ',' '                                 
             *,'?')                                   
)END


Panel B :
Code:
)ATTR DEFAULT(%+_)                                             
)BODY                                                           
%------------------  TITLE FOR MENU SELECTION PANEL  -----------
%SELECTION ===>_ZCMD                                           
+                                                               
+   THIS DIRECTION LINE TELLS THE USER HOW TO USE THE PANEL:   
                                                               
+   Enter below details:                                       
                                                               
+   Enter dataset name: _V1                                     
                                                               
+  %1+ Call Code REXXPROG                                       
   %2+ Call Dummy rexx                                         
)PROC                                                           
   &ZSEL=TRANS(TRUNC(&ZCMD,'.')                                 
             1,'CMD(REXXPROG)'                                 
             2,'CMD(PANEL1)'                                   
             ' ',' '                                           
             *,'?')                                             
)END


Panel C is somewhat same as panel B.
Rexx Code:
Code:
/* rexx */                     
if opt=2                       
   say 'You are correct'       
else                           
   say 'Option incorrect'     


My query is: I am not getting value opt = 2 in rexx program when I am selecting option 2 in panel A. Can any one please help me? I am getting value of opt as OPT.

Unless the panels are all displayed from within the same REXX code, which in this case I think not, then you will need to store the variable using VPUT from some code in the PROC section, and then retrieve the value in the next called panel.

Yup that' s right expat,

but I was adamant to suggest advanced techniques to somebody who , IMHO, still needs to grasp the basics

A sentiment I agree with 110%.

I always build my panels to all be called and controlled from within one REXX EXEC. That way it is clear what is happening and simpler to maintain or debug.

I guess Enrico and I and numerous others have been where you are now and know from bitter experience the easiest and cleanest way to do these things.
