The DOC command opens a explicit documentation file from the DOC directory or a BAT file from the BAT directory according to what it finds. For example "doc prepic" will bring up the documentation file for the PREPIC program, and "doc source_dir" will bring up the source_dir.bat file directly. Try that and you will see that the comments at the top of the file explain what it does. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
