subtract

procedure subtract[, in1][, in2][, out]

This procedure subtracts the data from two data containers stored in the global buffers 0-15.

If no parameters are passed, then the data from buffer 1 is subtracted from buffer 0 and the result is stored in buffer 0. If two parameters are supplied, the second is subtracted from the first and the result is stored in buffer 0. If three parameters are supplied, the second is subtracted from the first and the result is stored in the third.

out = in1 - in2
