Memory Usage,
C–6
The number of instruction words used by an instruction is indicated in the
following table. Since the program is compiled by the programmer, it is only
possible to establish estimates for the instruction words used by individual
instructions. The calculated memory usage will normally be greater than the
actual memory usage, due to compiler optimization.
