### ALP3754: Cannot determine calling convention

A procedure was defined to accept arguments passed on the stack by a calling routine, but no language attribute was specified or assumed for the procedure. The language attribute determines the calling convention, which in turn defines the order that arguments are pushed onto the stack.

Recovery: Use one of the following constructs:

Specify an explicit language keyword in the body of the PROC directive.

Specify a .MODEL directive with a language keyword argument.

Specify an OPTION LANGUAGE directive.
