110801 CRU: Convert, Compress and Restore File Utility Version: July 1985 Submitted by: Gilbert J. DeLeeuw, Cardiology Consultants, Philadelphia, PA Operating System: RSX-11M V4.1D Source Language: MACRO-11 Memory Required: 16.2KW Keywords: File Management Abstract: This program is primarily designed for operations on text files, and includes the following options: . Converts files between fixed and variable length records . Converts carriage control types (FORTRAN, LIST, and NONE) . Converts between 8 column tabs and spaces . Truncates or padds records . Removes trailing blanks and tabs from records . Selects a range of pages for output . Compresses (or restores) records The compression algorithm is based on repeat characters, and is therefore especially effective on reducing the storage required for files which contain significant amounts of filler (spaces) or nulls. The program was written in MACRO-11 and uses large buffers for efficient processing. Restrictions: Carriage control conversion from FORTRAN to LIST does not support overstrike.
