There's no BALR in the code snippets you've shown. I'll assume you mean BASR.

Two basic approaches: Top Down and Bottom Up. Start at the bottom -
what is the failing address causing your PIC 10? Does it look
plausible for the AMODE you're in at the time? Which instruction
actually failed? Is the failing address (or a near or left-truncated
version of it) in a register?

Etc...

If that hasn't made the problem obvious, then you may have collected
enough information to work from the top down. If it's true that the
ESTAE is provoking the failure, then what does it change, i.e. how
could anything it does affect the result of calling IKJPARS?

Etc...
