what do you guys do to compress files within a program euphoria?
Before I used a copy of gzip.exe, but now it no longer works.
res=system_exec("gzip -c -9 ultmov.txt > ultmov.gz",0)
Any idea?

That should still work. What happens if you manually attempt to run gzip from the command line?

In command line works well
But inside of a program, as above, res = 1
running my program in. exe, prompt in the last lines that appear are showing an error

Hmm.. instead of telling gzip to send the compressed output to stdout and redirecting that into a file, have you tried using the keep option? (Requires gzip 1.6 or later)
Or copying the original file first and then running gzip on the copy?

My version is deprecated.
gzip -V
gzip 1.3.12

I missed that you said gzip.exe earlier. This works fine on a sane OS, but you can't do redirection with system_exec() on Windoze. That never worked.
Copying the original file and then compressing the copy with gzip (without either -c or redirection) should still work with system_exec(). This is probably the easiest method, if you have enough space to make a full sized copy of the original file.
Or you can use system(), and find some other method to determine if gzip was successful or not. (Perhaps an MS-DOS batch script that writes the return code of gzip into a text file.)
Or you can use pipeio and write code to take the output of gzip and place it into a file yourself.

following your instructions
res=copyFile ("ultmov.txt","c:\\001Stok\\ultmov.txt",1) res=system_exec("gzip -9 c:\\001Stok\\ultmov.txt ",0)
is now working
Thanks jimcbrown
