IVRSID
1
in terms of bytes. Examples systems are:
DOS PC
Direct access record length unlimited, and defined
2
in terms of short words (2 bytes). Example systems
are:
Prime mini-computers
Direct access record length limited to 32 bytes, and
3
defined in teems of long words (4 bytes) Example
systems are:
DEC Vax
Direct access defined using multiple sequential
4
access files that are opened as required. Note that
this may generate and leave many files on disc.
Example systems are:
APPLE MAC II under ABSOFT FORTRAN
Definicon 020 beard, DEC Vax to avoid short
record lengths
HP Workstation
Direct access defined for a system using 64 bit or 8
5
byte words and where record lengths are defined in
bytes. Example systems are:
Cray Y-MP or Cray C90
Direct access defined using multiple sequential
6
access files that are opened as required. Note that
this version does not put a period (.) in the file
names. It may generate and leave many files on
disc. Example systems are:
CDC Cyber
