LITLINK
Makes the Compiler declare the literals in CALL literal statements as public symbols, so they are resolved at link time rather than run time. (Calls generated in this way are referred to as litlinked.)
LITVAL-SIZE
Specifies the number of bytes to pass if the SIZE clause is omitted when passing numeric literals BY VALUE.
RTNCODE-SIZE
Specifies the size of the RETURN-CODE special register and its alignment in memory.
PPLITLINK
Makes the Compiler declare literals as public symbols, in a SET statement using a data item defined as USAGE IS PROCEDURE-POINTER. This means literals are resolved at link time rather than run time. (Symbol references defined in this way are referred to as litlinked.)
