Heathkit H-89 program detects source code lines too long for the MBASIC compiler

Microsoft MBASIC saved its files in a compressed tokenized format. Before compiling a program with the MBASIC compiler, it was necessary to save the file in ASCII with the SAVE ,A switch. However, doing that made the lines longer, and the compiler would not compile lines longer than 127 characters.  

This program scans the ASCII file and tells you if any lines exceed 127 characters.
