I did wrote a module with the #for and #do commands some 
time ago, and it even was discussed here. But it wasn't 
put neither into the distribution, nor into the 
repository, I don't remember why. So, it's ok with the 
loop command, I guess.

The module itself, just as an example, is in the 
attachment.
