Is it possible to append to another file via redirection in Gulam?
The manual doesn't mention this anywhere and I thought it may be less than
obvious about how to go about doing it. I would just like to do a simple
'czprint filename >> datafile' (Czprint dumps data to the standard output).
Anyway, I found an indirect way of doing this, but it has one side
effect. First, my shell file looks like this....
foreach i { *.cz }
czprint $i
endfor
This script is executed via the command line 'catalog.g > datafile'.
Althought the script works to completion, the datafile doesn't have an
end-of-file terminator in it. When I edit the file or print it out (ie,
with LESS), the editor crashes when it gets to the end of the file!
Is this a bug with Gulam????JOE@rcgl1.eng.ohio-state.edu (Joe Rohde) (02/11/89)
Has anyone tried to set the variable (nrows i beleive) to set the screen to 50 rows in high res? when i set it, my screen clears produces the same number of rows, allows only 3 or 4 rows at the top to be used and gradually produces garbage at the bottom of the screen that rises to the top as return is hit. Am i doing something wrong/stupid? or has this never been fully implemented? Thanks, Joe Rohde rohde-j@eng.ohio-state.edu

In gulam the foreach command can be used to do something for each file
in a directory. The if command can be used to test whether the file is
a regular file a directory, etc. Is there some way to test what the
extension on a file is? I don't see how to do this from reading the manual,
but maybe I have overlooked something.
The following (except for syntax errors) suggests what I would like to do
foreach ...\i { * }
if $i.arc
arc -l $i
ef
echo $i
endif
endfor
With a valid test for the arc extension, this file would produce a listing
of the contents of all arc files and the name of all other files.
(Note, it is easy to do half the job: foreach ...\i {*.arc} will get
all the arc files; the hard thing is to dget the non arc ones.)bammi@curie.ces.cwru.edu (Jwahar R. Bammi) (09/07/90)

Not directly, but you can run an external program, and test its return
status with an 'if'. the return status of the last command is recorded in
the shell variable 'status'.

You don't have any kind of string processing in Gulam. -- Dipl.-Inform. Rainer Klute klute@unido.informatik.uni-dortmund.de Univ.
