Conditional Execution
All instructions in the MCxxxx programming language are capable of conditional execution. Prefixing an instruction with a “+” or “-” symbol will cause that instruction to be enabled or disabled by test instructions. When an instruction is disabled by a test instruction, it will be skipped and will not consume power. Instructions with no prefix are never disabled and always execute normally. All conditional instructions start in a disabled state. A test instruction must be executed to enable conditional instructions.

Conditional Execution
All instructions in the MCxxxx programming language are capable of conditional execution. Prefixing an instruction with a “+” or “-” symbol will cause that instruction to be enabled or disabled by test instructions. When an instruction is disabled by a test instruction, it will be skipped and will not consume power. Instructions with no prefix are never disabled and always execute normally. All conditional instructions start in a disabled state. A test instruction must be executed to enable conditional instructions.

all `+` and `-` statements start off disabled which means you have to execute a test insn first. the only test insn you have is prefixed with a `+` which starts off disabled, so it's impossible to have it be enabled. so don't put the `+` in front of the `teq`, put the `+` in front of the statements you want to be affected by the `teq`.
