CALL addr
Subroutine call
Description
The instruction unconditionally calls a subroutine located at the indicated
address. The program counter increments once to obtain the address of the
next instruction, and pushes this onto the stack. The indicated address is
then loaded. Program execution continues with the instruction at this ad-
dress.
