5-14 Data Movement
This section describes the instructions used for moving data between differ-
ent addresses in data areas. These movements can be programmed to be
within the same data area or between different data areas. Data movement is
essential for utilizing all of the data areas of the PC. Effective communica-
tions in Link Systems also requires data movement. All of these instructions
change only the content of the words to which data is being moved, i.e., the
content of source words is the same before and after execution of any of the
data movement instructions.

TC numbers cannot be designated as D to change the PV of the timer or
counter. You can, however, easily change the PV of a timer or a counter by
using BSET(71).
