3.1.7.3 Count loop (FOR ... TO ..., ENDFOR)
The count loop is used if an operation must be repeated with a fixed number of runs.
Syntax
FOR <variable> = <initial value> TO <end value>
...
ENDFOR
Meaning
FOR:
ENDFOR:
<variable>:
<initial value>: Initial value of the count
<full-scale
value>:
478
Initiates the endless loop.
Marks the end of the loop and results in a return jump to the beginning of the loop.
Initiates the count loop.
Marks the end of the loop and results in a return jump to the beginning of the loop,
as long as the end value of the count has still not been reached.
Count variable, which is incremented from the initial to the end value and is
increased by the value "1" at each run.
Type INT or REAL
Note:
The REAL type is used if R parameters are programmed for a count
loop, for example. If the count variable is of the REAL type, its value is
rounded to an integer.
Condition: The start value must be lower than the end value.
End value of the count
