I use Windows gzip/gunzip from:
http://gnuwin32.sourceforge.net/
In J7, I can use them the following way, once gzip and gunzip have been
installed in a directory in my PATH. An alternative would be to reference gzip
and gunzip with a fully specified path. yy contains the fully specified file
name that I am working with.
spawn_jtask_ 'gzip -v ',yy
C:\Users\me\j64-701-user\temp\foo1.ijs: 68.2% -- replaced with
C:\Users\me\j64-701-user\temp\foo1.ijs.gz
spawn_jtask_ 'gunzip -v ',;yy,'.gz'
C:\Users\me\j64-701-user\temp\foo1.ijs.gz: 68.1% -- replaced with
C:\Users\me\j64-701-user\temp\foo1.ijs
