Hi,
Are you under CICS? If so, the limit is 32K only and even then, IBM highly suggests to use only 24K because it reserves the right to use 8K for further enhancements.
So, there are other techniques to achieve it (either using TSQ to exchange data between two pgms, or passing a pointer to a memory zone that contains the data, etc.).
Hope this help,
Alain |

I have passed messages as big as 4MG in my IMS COBOL linkage. For ha-has, I tried to see how big a hold area I could make for my buffer. The compiler we have here would not allow any field over something like 16.4 meg.

| Slight correction. Depending on version of Compiler and CICS. The maximum length for a Getmain is 64K and if using above the line Extended Dynamic Storage it can be more (based on the definition of your EDSA resource allocation). |
