Operative Flags: None
Flags Affected: None
Example: SAGT 0x8
Inst1
Inst2
After Instruction
If ACC = (or <) 0x8, `Inst1’ is executed.
If ACC > 0x8, `Inst1’ is discarded, and `Inst2’
is executed.
SALT L
Function: Skip the next instruction if ACC less than
immediate constant.
Operation: Skip next if ACC < L
Operand: L: 4-bit immediate constant
value, 0x0 to 0xF

Example: SALT 0x8
Inst1
Inst2
After Instruction
If ACC = (or >) 0x8, `Inst1’ is executed.
If ACC < 0x8, `Inst1’ is discarded, and `Inst2’
is executed.
SAEL L
Function: Skip the next instruction if ACC equal
immediate constant.
