Hi, I've coded a function (see below) with a sequence of Cases in a Select Case > End Select statement.
However, when my code runs, the first Case is matched and processes the contained statements - as expected - but then proceeds straight to End Select instead of dropping down to the next Case!  How to I get the code to evaluate each Case in succession as described in the documentation
(/lang/select - Gambas Documentation)?
(The msExists function call should return True in each Case statement, so processing all the code.)

 That is how it is designed to work.
If you want to test for multiple conditions then Select is not what you want.
AFAICS what you appear to need is just a successive set of If's.

p.s. I don't see how you got that idea from the indicated help page, what was unclear?
p.p.s Select Case True is not sensible. It will always be true, as in If True=True then …

You can't , that's not how Select works.

It Selects the first True condition.

Use If blocks , Select case is like using If and Else if
When it finds a condition to be true it will only run that bit of code and ignore the rest.
Like it Selected it.

I changed the first line of the wiki page

from this..
Selects an expression to compare, and execute the code enclosed in the corresponding matching CASE statement.

Selects one particular condition from a group, and executes only the code enclosed in the corresponding matching 'CASE' statement.

So it's clearer that the "Select" function in mono-conditional and woks as a Selector for a single Case.

PS. Drop the Case word from the Select Line, it's just confusing.

So it's like this…

hi All, thanks for the correction of my assumptions :roll: , and the useful tips.
The most misleading bit of the wiki document for Select is shown in bold:-
_____________________________
Note
The TO keyword can also be used without a lower bound which makes the case like a less than range. For example.
  CASE TO 0
will act as CASE < 0 and since the cases are evaluated in succession

It would be even better  if it said "the first case encountered that evaluates true ignoring the remaining" or words to that effect.

Consider
In that case (sic) it will do whatever.
Also consider what happens if x = -7 and we change the Select expression to !
