Operation
IF (op1) THEN
ELSE
END IF
Description
If the condition specified by op1 is met, a branch to the location specified indirectly by
the second operand op2 is taken. The value of the instruction pointer IP is placed onto
the system stack. Because the IP always points to the instruction following the branch
instruction, the value stored in the system stack represents the return address of the
calling routine. If the condition is not met, no action is taken and the next instruction is
executed normally.
