Operating System Routines
You must verify that the actual parameters in the ENTER statement (including
return-value in the GIVING phrase) are of the HP COBOL types that correspond
to the TAL types of the formal parameters in the operating system routine. The
compiler performs the necessary conversions of sending parameters. Parameters
passed by reference must match exactly. The HP COBOL data type INDEX does not
correspond to any TAL or pTAL data type.
