Basic lang syntax

[canalrun]

Hello all,

I have been off doing other languages and I don't remember some of the syntax details in the Basic language.

For example if ((a < b) and (c < d)) …
Is it supposed to be "and" or "&" or "&&" or something else?

Or for a range in the Select/case …
Is it "case 1 to 5" or "case 1-5" or something else ?

Is there a manual, section, or webpage that goes through this stuff for B4A?
I have found the help viewer, but I can't seem to find this information in my searches.

Thanks,
Barry.

Is it "case 1 to 5" or "case 1-5"

"1-5" is indistinguishable from an arithmetic expression which evaluates to minus 4, so that would have been a Bad Choice!

And to include ranges like that would suggest an If statement rather than a Select...

Sorry, I don't agree.
For example

Select Case Value
Case 1 To 5, 7 To 9
Case 6
End select

does exist in VB, and I used it quite often.
I was missing it too, but adapted my code to the B4PPC and B4A requirements.

Attention: in B4A it's Select Value unlike Select Case Value in VB.

Thanks.
And thanks for moving the thread.
I had already posted when I noticed it was in the wrong place.

I agree, a range is handy to have in a Case statement.
But, it is easy to get around it by using an If.
