ABSTRACT ________ TIDY is a program to straighten MACRO-11 source source code. The user is requested to enter the files names in the format: input-file/output-file. The program reads the input file, one line at at time, and generates the straightened output line and writes it to the output file. The columns for each of the field are defined by constants in the subprogram STRATE and may be changed as necessary. Executable statements inside macros are adjusted to the normal column filed of normal statement comments so that they won't be confused with actual source statements but are still available to those who use macro expansion. To run the program type: RUN TIDY and when asked for the file names, enter them as specified above. The program will also print the number of lines straightened and the amount of time it took upon completion.
