I noticed something weird when testing an SQL program I am writing. The
program parses message queues in search of escape messages.

The message data is then received in a character variable for later
processing.



But if I define the receiving variable like this:



dcl-c Used_Ccsid 278;

dcl-s Messtxt char(100) ccsid(Used_Ccsid);



The SQL fetch fails with SQLSTATUS 57017 ?Character conversion between
CCSID 1200 and CCSID 65535 not valid)



Whereas if I define the ?Messtxt? variable like this

dcl-s Messtxt char(100) Ccsid(278);



It all works fine



Normally defining various features of variables using constants for say
number of digits, sizes or similar works perfectly fine.
