probably your question is as follows:
maia% a = `{ls file}^test; echo 'this part is not executed if file doesn''t
exist'
ls: file: 'file' directory entry not found
rc: null list in concatenation
maia%
on the other hand,
maia% ls file; echo 'this part is not executed if file doesn''t exist'
ls: file: 'file' directory entry not found
this part is not executed if file doesn't exist
maia%
a similar thing is:
maia% (aa bb)=aaaa; echo bbbb
rc: variable name not singleton!
maia%
perhaps this is a feature.
rc stops execution if there is an error in grammar.
