110485 TREAD: Subroutines for Reading and Writing IBM Standard Label RECFM=FB Magnetic Tapes Version: V3.02A, July 1981 Submitted by: Frank J. Manion, CHI Computer Horizons, Inc., Cherry Hill, NJ Operating System: RSX-11M V3.2 and V3.1 Source Language: MACRO-11 Memory Required: Approximately 2KW Keywords: IBM, Magnetic Tape Handler Abstract: TREAD is a subroutine system which allows magnetic tape users to easily read and write IBM compatible magnetic tapes at 800 or 1600 bpi. The tapes to be read or written may contain data in any size fixed-length records. The logical records may be blocked or unblocked. Input tapes can be properly read if they contain IBM standard labels, non-standard labels, ANSI standard labels, leading tapemarks, or no labels. Output tapes can be written with IBM standard OS/VS labels or no labels. Translation from EBCDIC to ASCII on input, or from ASCII to EBCDIC on output is available to the user as an option. Multiple reel input and output is supported. Input and output tapes may contain more than one data file. The subroutines are user friendly in that they relieve the user of most of the burden of error handling. The routines also include extensive runtime diagnostic messages. Restrictions: Has not been tested under IAS or RSX-11D. Media (Service Charge Code): User's Manual (EA), One RX01 Diskette (KA) Format: FILES-11 OR RT-11, 600' Magnetic Tape (MA) Format: DOS-11 OR FILES-11 MEDIA FORMAT MUST BE SPECIFIED ON ORDER FORM
