DRL RSTSWH (octal 11) - reset switch word.

Usage:

ldq    bits
drl    rstswh or rstswh,*

Description:

DRL RSTSWH is similar to DRL SETSWH except that each bit in the Q-register that is on causes the corresponding bit in the switch word to be turned off. The resulting value will be returned in the Q-register. If the * is not specified, the primary switch word (.LSWTH) is affected; if the * is specified the second switch word (.LSWT2) is reset.
