Re: [Reduce-algebra-developers] Where to find documentation about REDUCE command line arguments?

[Martin G. <mar...@ic...>]

I don't have access to microsoft windows, but on Linux the corresponding
redpsl script calls bpsl which also does not respond to --help, -h, -? 
and just passes whatever arguments you specify to the reduce image. 
redcsl --help does work.

Since you are running a .bat file, did you try /help, /h or /?

I also prefer running in batch and use the following script, perhaps it
works for you with tweaking of paths. The script allows me to specify
either psl or csl and a list of scripts, each of which is executed in a
separate session and produces a transcript by appending "rlg" to the 
script name. If no files are specified it starts an interactive session.

Martin
