High-level -- just as all BASIC/COBOL/C/Etc commands are high-level
representations of many more assembly language commands.
For-next:
Start-Value = 1
End-Value = 99
Increment = 1
Counter = Start-Value
:Start-For
If Counter > End-Value Then
Goto End-For
end-if
do stuff
Counter = Counter + Increment
Goto Start-For
:End-For
In fact there could be times when you would want to do this this way
instead of using a for-next -- as in if you want you increment to change
each time, or if you want to repeat a single iteration until some other
condition is met.
