How to retrieve return value of RUNEXE and also RUNSCRIPT?

Question

In a macro file (*.do) in ALDEC Active-HDL 9.2, I am looking for a way to retrieve some kind of return value of an external executable (run by the runexe command).

So is there a way to retrieve the exit code, or to capture the console output (from stream STDOUT or even STDERR)?

Something like set return [runexe -wait -capture cmd /D /S /C exit 1]; echo $return does unfortunately not get the exit code 1, neither does set return [runexe -wait -capture cmd /D /S /C echo Result]; echo $return fetch the STDOUT output stream.

Do I miss something, or is something like that simply not supported?

If so, could such data be read from a (text) file as an alternative solution?

And by the way, is there a way to retrieve some kind of return value of a sub-macro (another *.do script run by the runscript command)?

Answer 1

The only work-around I found so far is to let the sub-executable write a variable definition statement to a temporary macro, like:

# write result to temporary `*.do` macro
# (`setenv` is needed instead of `set`):
runexe -wait -capture cmd /D /S /C {echo setenv var Test_1> temp.do}
# retrieve the resulting value:
runscript -do temp.do
echo $var
# clean up temporary macro:
runexe cmd /D /S /C del temp.do
