8.15.15 RESET (R)
Syntax: R (RESET)
Operands: M, I, O, T, C
Action:
If the logic accumulator = 1, then set the addressed operand to 0, otherwise 
do not change it. Use the R command at the end of a sequence of logical 
gating operations in order to influence an operand, depending on the result of 
gating. This command can be used several times in succession (see example).
Example:
Gate input I4 and I5 with OR. If the gating result is 1, then reset output O2 and 
marker M500. 
Initial state: 
Input I4 = 1 
Input I5 = 0 
Output O2 = ? 
Marker M500 = ?
