Very Confused

[Del]

Greetings:

I am writing an output process to copy data from one qualifier to another (processing only, no print).
I am running it on a new HP PC operating under Windows 7, very fast.
I have a show command that displays account numbers on the screen as it processes all the accounts. 
The idea is to give the end user something to look at to reassure them that the process, which takes a while to cycle through all the accounts, is actually running and not hung up – seeing the account numbers cycle on the screen does that.
However, when I initially tested it, nothing showed on the screen.  
I went into debug mode to see what was wrong and the show command worked fine in debug mode (did not make any changes).
I started to think that maybe the system was so fast that the show output never made it to the screen before it was wiped out by the next show command – is that possible?
So I put a pushkey “[ENTR]” command just before the show command and an x=waitkey right after it.
The idea being to actually slow it down a bit.
Voila!  The show command then displayed on the screen just fine.
But why did I have to do this?  And what should I have done?
