RETURNS

OpenVMS usage:	cond_value
type:	longword (unsigned)
access:	write only
mechanism:	by value

Arguments

context

OpenVMS usage:	context
type:	longword (unsigned)
access:	modify
mechanism:	by reference

Message context information to be passed to message routines. The context argument is the address of a longword that contains message context information.
