 *  This program takes a Laboratory Microsystems Z80-FORTH screen file  *
 *  and creates a text file from it.  The output format is similar to   *
 *  the format used by Z80-FORTH for listing screens but can be		*
 *  redirected to any device supported on CP/M, or to a disk file which *
 *  can then be edited.  This program can be compiled with the Software *
 *  Toolworks C80 compiler.						*
