Thanks for posting that. It looks like adding the ".thumb_func"
directive before a function would eliminate the need for the "... + 1"
in my vector table.

Somehow, I think your programs would feel *larger* if you used TECO,
while actually remaining the same size. ;)

Thanks, but I don't know how to interpret your source and find
statements.

Probably painful experience ;) Carrying on from above, if a "high level language" is a time multiplier, safety certified code is a time divider. We have a "moderate" safety piece of code whose executable file is 22K bytes and the corresponding documentation, test procedures/reports, etc is probably pushing 1000 pages ...
