evaluate the "it" variable in an external

[Mark Wieder]

Correcting my own post:

tested:

void RevClipsAsk(char *args[], int nargs, char **retstring, Bool *pass, Bool *error)
{
        int     retval;
        char    *actualResult="test";

        SendCardMessage("put revClipsAsk() into global clipsResult", &retval);
        actualResult = GetGlobal("clipsResult", &retval);
        *pass = False;
        *error = False;
        *retstring = istrdup(actualResult);
}

from Transcript:

function revClipsAsk
  ask info "Your input:" titled "CLIPS input"
  if it <> empty then
    put it into clipsResult
    return it
  else
    put the result into clipsResult
  end if
  return the result
end revClipsAsk
