While-Wend (and Do While/Do Until) is just a shortcut for using If/Goto:
Do While Flag <> True
do some stuff
If condition then
Set Flag to True
end-if
loop
is the same as
:loop-in
If Flag = True Then
Goto loop-out
end-if
do some stuff
If condition Then
Set Flag to True
end-if
Goto loop-in
:loop-out
Spaghetti code is caused by bad programmers, not bad programming languages.
