Reply with quote

Hello People,

I wanted to know if there is any way in CLIST to identify symbol '&' in a string. I want to handle a situation in my CLIST where if the input string passed to CLIST contains '&' then do XYZ (for say)

At the moment its not accepting any CLIST inbuilt functions which i can use to check if '&' is present anywhere in the string.

I always receive an error with function used saying :-

IKJ56545I THIS STATEMENT HAS AN INVALID SYMBOLIC VARIABLE


Thank You,
Rajat

Have you tried "doubling it up"?

I don't suppose so many people actually write CLISTs today. So much easier to code, maintain, understand in Rexx.

And of course, don't forget to blow the dust off the manual.

a yes/no question deserves a yes/no answer

YES... it is possible (there are gazillions of legacy clists doing it)

we are in the 21st century, not in the stone age
why keep writing things using an obsolete <language>
use REXX

worth spending a bit of time learning it,
You and Your organization will enjoy a much faster delivery time

and finally why not do a bit of research Yoursef
reading the manuals or lazily googling for clist ampersand processing

HI..as Bill suggested..try doubling it up..I had faced a similar problem in REXX...where I had to use '&&&&' to identify a single '&'.

ok..its going to be a long post:

The Purpose of this REXX code was to search for the OLD string and replace it with a new string in a PDS.

Rexx Main Code:

Code:
/******************REXX*******************/

ISREDIT "END"                   
EXIT   


When you will execute the main REXX it will show you below Panel, which will ask you to input OLD string, New String and PDS name.
Here My Inputs are:
OLD STRING = &AB
NEW STRING = &CD


Code:
---------------------------------------------------------------------

 <PF1>=HELP               ENTER-TO PROCESS             F3- END/CANCEL


My INPUT PDS has a member which has foloowing data:
Code:
000001 &AB1 
000002 &AB2 


It does not change &AB to &CD , but if my inputs are &&&&AB and &&&&CD then it does the change.

Please let me know if you need more information.

unfortunately Your evidence is due to a poor understanding of
the ISPF SCAN behavior and of the proper coding technique for compliancy

this is a tested CHGALL application ( WYSIWYG )
probably a bit more sophisticated than Yours

the REXX driver

there is still the glitch of the CAPS for the changed strings
but that' s something easy to take care of

Hi Enrico.

Thanks for your code..I will try and run your code tomorrow..I'm not working today.

But I was just wondering how it would handle the scenario that I mentioned..like say, if I want to change DSN=&&ABCD to DSN=&&TEMP

Properly... what else icon_cool.gif

Code:
-------------------------------------------------------------------------------
---------------------------------- Change all ---------------------------------
-------------------------------------------------------------------------------
COMMAND ===>

-------------------------------------------------------------------------------
 Dataset        ==> enrico.test.pds

-------------------------------------------------------------------------------
 From String    ==> &&prev
 To   String    ==> c'&&TEMP'

-------------------------------------------------------------------------------
 Options        ==> ALL
 Mbr  Filter    ==>

-------------------------------------------------------------------------------
 Excl Trigger   ==>
 Incl Trigger   ==>


I fixed also the capitalization problem ..
note that now the syntax for the from and to strings is the same as the one used for the CHANGE command


do You want me to upload the whole shebang again ?

Hi Enrico

I'm still learning..so probably you can ignore my naïveté, which led me to post that comment.

No..that's not required..I can take it from here :-)

Thanks again !!

the changes spread a bit all over, it will be easier for You to have the whole picture

Yup..I did notice the smiley..but looking at your code(and then mine) made me say that :-)

here is a modified and enhanced version

note note note
the FROM and TO strings can be any valid FROM/TO string accepted by ISPF
done some elementary checking for bad tokens,
a symptom of a missing check is a return code of 20 fro edit

there are still a couple of glitches,
