What is $REE? That may through you a little... Also depends on where you do it from. If $REE is an environment variable, you may want to get that first. Also your " may be confusing the command as well.. Use \" instead. Try $REE = $ENV{REE}; system("cbsfpfg `echo \"esel\"$REE esel`"); [download]	[reply] [d/l]

If `$REE` is an environment variable make sure you `export` it. It may be available to you from the command line but not available to your script. (actually to the sub-shell created by the `system` which is a sub-shell of the shell running perl which is a sub-shell of the command-line shell). You may also need to escape the $ so it gets passed to the `system` and not interpolated as a perl variable. Of course everyone uses `strict` catch those kind of things, don't they? -- flounder	[reply] [d/l] [select]
