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.
