1
Direct access record length unlimited, and defined in terms of bytes.
Example systems are:
Definicon 032 board
M S FORTRAN for IBM micros
2
Direct access record length unlimited, and defined in terms of short
words (2 bytes).
Example systems are:
Prime mini-computers
3
Direct access record length limited to 32 bytes, and defined in terms of
long words (4 bytes).
Example systems are:
DEC Vax
4
Direct access defined using multiple sequential access file 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 board, DEC Vax to avoid short record lengths.
5
Direct access defined for a system using 64 bit or 8 byte words and
where record lengths are defined in bytes.
Example systems are:
Cray Y-MP or Cray C90
6
Direct access defined using multiple sequential 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
8
Same as 4 except PAUSE statement is activated
