[AccessD] Eval function

Back in the early releases of Access you could use the @ character to pretty up the default MsgBox display.  The @ character divided the display into 3 separate entities, the first bold, the second two not, each delimited by a blank line.  So, 
MsgBox "File missing at The file FredDagg is missing at Please correct and re-try"
would give you a nicely laid out msgbox.

Somewhere in the last couple of releases, Access changed where MsgBox was processed.  Somebody else will have to fill in the precise details here but the end result was that the @ characters were not recognised any more.  So, this was the workaround:  

     eval("Msgbox(""" & prompt & """, " & Buttons & ", """ & Title & """)")

Apparently the Eval takes the String passed to it, evaluates it, and then processes it as a line of code.  And it does give the nicely laid out msgbox. 

My 2cents
