SETPSW - set switch word by bitwise OR.

Alternate Entry Name: SETSWH

Usage:

B:
   newval = setpsw( bits1 [, bits2] );

C:
   int setpsw(int bits1 [, int bits2] );

Where:

bits1

is a word containing the bits to be ORed into the first switch word. The bits that are on in "bits1" will be turned on in the first switch word.

bits2

is a word containing the bits to be ORed into the second switch word. The bits that are on in "bits2" will be turned on in the second switch word. If "bits2" is not specified, the default is zero and no bits are turned on in the second switch word.

newval

is the new value of the switch word. If only "bits1" is supplied, "newval" receives the value of the first switch word; otherwise, "newval" receives the new value of the second switch word.

Description:

SETPSW turns on specified bits in the Program Switch Words (PSWs). Numbering left to right, bits 0 through 17 of the first switch word should normally be left alone, since they are used by supplied GCOS-8 software.
