NUMPROC"ACOS" sets SIGN"EBCDIC" and CHECKNUM.
If NUMPROC"ACOS" is specified with any of CHARSET"EBCDIC", HOSTNUMMOVE, HOSTNUMCOMPARE, SIGNFIXUP, or SPZERO, a severe checker error is produced (COBCH1266).
The directives HOSTNUMMOVE, HOSTNUMCOMPARE and SIGN-FIXUP should be used to configure compatibility with the processing of invalid data by IBM Mainframe COBOL.
The CHECKDIV"ACOS" directive provides further ACOS mainframe compatibility.
