There are straightforward ways to update [necessarily] DASD-resident

language supports these operations, and Enterprise COBOL certainly
does not. (An LE-compliant pair of COBOL-callable HLASM subroutines
would of course be easy to write.)

Assembler: use DCB MACRF=(GL,PL), open for UPDAT,
issue GET, change data, issue PUTX
COBOL: open for I-O, issue READ, change data,
issue REWRITE
DASD only.
Can also do for PL/I and, I believe, C.

Steve, I believe it MACRF=(GL,PM) for PUTX, isn't it?
