/******************************************************************************
MODULE
ScriptName.c
DESCRIPTION
Tries to recognize the name of the currently
active scriptfile.
NOTES
Kickstart 2.0+ required
compiles w/ SAS/C v6.51
BUGS
The result is most likely something like
'T:Command-??-T??' with ? being numbers,
if the system 'decided' to create a tempfile;
Up to now we can not get another result,
for if no tempfile is created, we get an
empty string =8-(.
