Hi folks,
what I'd like to see in VB7 is "EXIT IF".
So far we've got EXIT DO, EXIT SUB, EXIT FUNCTION, EXIT FOR and EXIT
PROPERTY. However, there is no way to directly step out of an IF-clause.

How about that?

IF fVB7 Then
MsgBox "Yes, I love my VB7"
If Date < #01/01/2001# Then Exit If
MsgBox "And it's finally here"
' Do some more stuff here
Else
' Do some other stuff here
End If
' Continue here after Exit If

What do you think about that suggestion?

CU

C and C++ both do that with "break." However, ask four people how it works,
and you may or may not get 4 different answers. I'm thinking that may not
be the best keyword to add.

I also wish to have "continue;" in for...Next similar to one in C/C++


Nowadays to work around nested and ugly if...tyen...else, I use do...Lopp
while (false)


valid_1 = True
valid_2 = False
valid_3 = True

Do

If Not (valid_1) Then Exit Do
If (valid_2) Then Exit Do
If Not (valid_3) Then Exit Do


Loop While (False) '---so that it executes only once.

If you make the assumption that the code can't be redesigned to eliminate
the problem altogether...why don't you just use a GoTo? I mean, it's what
you're doing, really, and using the Do...Loop (False) only obfuscates the
intent, IMHO.

Haven't you heard Colin? GoTos are the work of Satan.

I agree completely! Would very much like a continue key word. ****, even
the Unix Bourne script language has a continue command.

LOL. I vote for break/continue.

Wasn't aware that I had personally invented those. Ah, time flies. =)

No, but I'm serious; how was the fake do/loop proposed any better than a
GoTo?
