VBA has quite an orthogonal way to build loop control:
pre-checked positive:
Do While ...
...
Loop
post-checked positive:
Do
...
Loop While ...
pre-checked negative:
Do Until ...
...
Loop
post-checked negative
Do
...
Loop Until ...
"endless":
Do
...
Loop
There is a language called Pick Basic (which most of you have never heard
of) which has a single syntax covering all possibilities -
LOOP
{optional statements}
WHILE {condition} or UNTIL {condition} DO
{optional statements}
REPEAT
The DO and the REPEAT are necessary because it does not use indentation or
braces to terminate blocks, it uses keywords.
