Hi John!  I hope you're not seriously promising this
will be your last question on the subject!

You really write code like that?  Yes, they would be
valid.

Have you been programming in Perl lately?

Are you asking for something like this?

     CF  if %canupdate(reade)
     CF     update reade
     CF  endif

I'll add it to our proposed enhancements list.

But then again, you could always do:

     CF  update:e reade
     CF  if %error
     CF     -- handle error
     CF  endif

or perhaps in a future release:

     CF  monitor
     CF     update reade
     CF  on-error 1221
     CF     -- handle error
     CF  endmon

Cheers!  Hans
