Thank GOODNESS that the IBM file access and SYNTAX for BDAM (relative) and ISAM
(Indexed) files died a WELL deserved death. It was HARDLY a matter of ANSI/ISO
giving "blessing" to the IBM syntax (of rupport). Although IBM did keep support
for their earlier "attempts" thru the end of OS/VS COBOL (whether LANGLVL(1) or
(2) was specified), they did include full support for the '74 Syntax (and
eventually VSAM instead of ISAM) in OS/VS COBOL - and with VS COBOL II (and
later) these earlier formats are simply GONE.

I recently downloaded a scan of the ICL 1900 Cobol Manual from
icl1900.co.uk. Ah the memories. This compiler was a mix of '68 and '74
and had SEEK instead of the later START, and many other differences
from'74.
