...If your ascii files are in DOS rather than UNIX format you will not be able to generate proper TCL/TK code. The bar at the top of the form allows you to convert files from Dos to Unix if need be and check which format they are in.
The difference between Unix and Dos ascii format is the line endings. DOS uses carriage return and line feed ("\r\n") as a line ending, which Unix uses just line feed ("\n"). In VBA these are Chr(13) <- return and Chr(10) < line feed
