Issue/Introduction

When a multi-line message is appearing, a couple of rules are failing with below error:
OPS9999T OPAOEV RC= 46 FOR ENVIRONMENTAL VARIABLE MSG..0

What is causing the problem?

I have provided below from OPSLOG the message that is being trapped and the error message:

Please find below the rule that is getting triggered:

Resolution

You set the variable 'text' to a blank, then you use that same variable (maybe inadvertently) in a compound symbol, msg.text.0 - this variable reference resolves to msg..0 (as the variable text is now blank) so the error occurs trying to reference an invalid event variable.

Do not use the variables in compound symbols as 'single' variable references unless you really intend to - change text = ' ' to something like txt or mtext.
