Re: For Loop

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

I always use 32-bit integers (10i 0).  They are the fastest to 
increment, and you're not really saving any effort or making the code 
more readable (or anything else that I can fathom) by using a 3,0 packed 
decimal.  (Indeed, if anything, you're making the code more difficult to 
maintain because anyone who tries a number higher than 998 will have 
problems, and will have to stop and troubleshoot the new bug he's 
created...  )

What value do you derive from using 3p0?  What advantage does it give 
you?  (Saves you 2 bytes of memory! LOL!)
