Rexx, likewise. It would be so easy in syntax:
fopen( "//DD:SYSLIB(MEMBER)", ... );
I believe SAS/C does something like this.
It's a pity that QPAM isn't invented, sparing implementors
a level up the discomfort of block-mode access.
Or, use UNIX files instead of legacy. No allocation needed, and
the open/close overhead is vastly less. Are all the BPX1* routines
available in COBOL?
