Example
ABS
ABS (absolute value of a 32-bit IEEE FP) produces the absolute value of a
floating-point number (32-bit IEEE floating-point number) in ACCU 1. The result is
stored in accumulator 1. The instruction is executed without regard to, and without
affecting, the status bits.

STL Explanation
L ID8 //Load value into ACCU 1 (example: ID8 = -1.5E+02).
ABS //Form the absolute value; store the result in ACCU 1.
T MD10 //Transfer result to MD10 (example: result = 1.5E+02).
