Hmmm....

I wonder if it would be more efficient to save a couple of process creations...

  :xeq /bin/awk "'BEGIN {print !V1 + !V2}'"
  35.8

  :xeq /bin/awk "'BEGIN {print int(!V1 + !V2)}'"
  35


One could use a TEMP file to capture and input the result...

  :xeq /bin/awk "'BEGIN {print int(!V1 + !V2)}'" >sum

  :input result <sum


Or you could let awk output the SETVAR command...

  :xeq /bin/awk "'BEGIN {printf(""setvar result,%i\n"", !V1 + !V2)}'" >cmd

  :xeq cmd


Of course, you could also waste a child process by awk invoking callci setvar...

  :xeq /bin/awk "'BEGIN {sum=int(!v1 + !v2); system(""callci setvar uv,"" sum)}'"


Okay okay... I'll shut up now ;)

Cheers, Lars.
