Re^2: write from filehandle to variable

Thank you for the reply..........I'm pretty green at this. I'm not quite sure which parts of your reply I am to substitute my own names, or files for (i.e. $fh 'moo!', etc.). Could you clarify? Which parts of your code other than the variable name, would I change?

If I understood your original question correctly, you wanted a file handle which wrote to a variable instead of to a file. `$fh` is the file handle. `$var` is the variable in which the text ends up. `'moo!'` is the text being written to `$var`.	[reply] [d/l] [select]
