I am a bit puzzled by what I am seeing when I utilize this compile option because it seems to indicate there is a problem there is not.   I have this snippet of code you see below my name.  This variable  LK-RESPONSE-MSG-XML was set to the address of this pointer WS-REQMSG-XML-PTR  which is a getmained area of storage. Problem is when the string command is executed get an error IGZ0074S to the effect value in   WS-RESMSG-XML-LEN points beyond the right most character of   LK-RESPONSE-MSG-XML. My expectation is SSRANGE will flag  something that is actually a problem but in this case it appears to flagging something can only be coded one way.If SSRANGE flag things that may or may not be a problem I question the value of it.

What are the working-storage definitions for these fields?

This field LK-RESPONSE-MSG-XML  is defined at 6K in size The application then does a GETMAIN for 10K and there in lies the problem cause SSRANGE works off the field definitions.  The solution per Tom Ross of IBM (i.e. Captain COBOL) is to define LK-RESPONSE-MSG-XML  with a size of the largest message size you want to be able to process. Because LK-RESPONSE-MSG-XML   is defined in the linkage section there is no adverse effect on the program cause it only GETMAINS the amount of storage required. Tried it out today and it ran like a champ.

Yep, that sounds right to me.

You didn't supply your actual definition, but you might look in to defining it as something like the following:

01  LK-RESPONSE-MSG-XML.

    05  PIC X OCCURS UNBOUNDED DEPENDING ON WS-RESMSG-XML-LEN. 

Just a side note, but you don't need to set a pointer and then set the address of the message from that.  You can just do this:

EXEC CICS GETMAIN                     

           SET     (ADDRESS OF LK-RESPONSE-MSG-XML) 

           FLENGTH (WS-RESMSG-XML-LEN) 

           INITIMG (WS-SPACES)         

 END-EXEC.                              

Thanks so much for the reply. I did not write the code I inherited the code.  Never the less I think I will incorporate your suggestions
