Are any possible commands on data in a field also possible in a variable ?

Good practice could be:

1. If you can, always use variables:

local tData
-----
put field "Data" into tData
< data processing>
put tData into field "Data"

2. If using variables does not appear possible, always think of  
locking and unlocking the screen appropriately:

lock screen
   repeat 100
      CreateNewField -- custom handler
   end repeat
unlock screen
