[open-cobol-list] Re: Linkage Section and maintaining addressability

[Roger While]

Bill,
Micro Focus does NOT, per default, save addressability over call's.
Attempting to reference a non-passed formal linkage-section parameter
(that has not been the subject of a SET ADDRESS OF) results in a 203 error.

This changes when implicitly (via DIALECT option) or explicitly setting
the STICKY-LINKAGE option.
Info on this option at :
support.microfocus.com
Documentation -> Server Express 4.0 -> Reference -> Compiler Directives.
