If I have a script file called with no args that starts:
==================================
if (arg(0) eq 0) do
win.debug("0 args")
else
win.debug("1 arg")
endif
[EMAIL PROTECTED]
quit
@testArg1
if (arg(0) eq 0) do
win.debug("0 args in labelled sub")
else
win.debug("1 arg in labelled sub")
endif
quit
==================================
output is:
0 args in labelled sub
1 arg
looks like arg(0) is the null string on entry to a script file taking
no args.
Testing length of arg(0) -- or even if (arg(0)) -- will do as a
workaround.
