The concept of ContinueCase

[asdf8]

At this point, the operator ContinueCase is an operator unconditional jump in the operators conditional jump Select and Switch. And he was more in line with the name NextCase.

If you want to really check out some conditions Case, you have to write code like this:

expandcollapse popup

$var = 4
$iFlagCaseElse = 1
Select
Case $var > 2
  If $var > 2 Then
   $iFlagCaseElse = 0
   ConsoleWrite('-> ' & $var & ' > 2' & @CRLF)
  EndIf
  ContinueCase
Case $var < 2
  If $var < 2 Then
   $iFlagCaseElse = 0
   ConsoleWrite('-> ' & $var & ' < 2' & @CRLF)
  EndIf
  ContinueCase
Case $var > 6
  If $var > 6 Then
   $iFlagCaseElse = 0
   ConsoleWrite('-> ' & $var & ' > 6' & @CRLF)
  EndIf
  ContinueCase
Case $var > 8
  If $var > 8 Then
   $iFlagCaseElse = 0
   ConsoleWrite('-> ' & $var & ' > 8' & @CRLF)
  EndIf
  ContinueCase
Case $var < 8 And $var <> 2
  If $var < 8 And $var <> 2 Then
   $iFlagCaseElse = 0
   ConsoleWrite('-> ' & $var & ' < 8' & @CRLF)
  EndIf
  ContinueCase
Case Else
  If $iFlagCaseElse Then
   ConsoleWrite('-> (Case Else) $var = 2' & @CRLF)
  EndIf
EndSelect

My question is - can change is the concept of ContinueCase?

[ripdad]

My logic is not always right -- sometimes, I have to change it.

Take for instance, these two lines are exactly the same:

Case $var > 2
    If $var > 2 Then

Do you see any difference? Case is an IF Statement.

Would you like to modify your code?

No. You only can use other Autoit statements like If Then Else etc.

[asdf8]

Would you like to modify your code?

If you remove If ... Then, get this:

$var = 4
Select
Case $var > 2
  ConsoleWrite('-> ' & $var & ' > 2' & @CRLF)
  ContinueCase
Case $var > 8
  ConsoleWrite('-> ' & $var & ' > 8' & @CRLF)
  ContinueCase
Case Else
  ConsoleWrite('-> Case Else' & @CRLF)
EndSelect

Is there a real case you try to solve or do you just want to see how ContinueCase works?

[ripdad]

yes.

now ... do you have to check every Case ... or just one?

think about it.

[asdf8]

Is there a real case you try to solve

Of course there is, and i know how to solve it without using Select or Switch.

The situation I described in the first post.

asdf8,

I find your script in the first post a very confusing example of how the current implementation functions - I suggest something like this explains more clearly the current ContinueCase:

Switch $iVar
    ; Save and exit
    Case 1
        ; Do saving of vars etc here
        ContinueCase
    ; Exit directly
    Case 0
        ; Clean up code goes here and is run in both cases
        Exit
EndSwitch

Are you suggesting that the function should be renamed "NextCase" and retain the same functionality - or are you suggesting that the functionality should be altered - or both - or something else entirely?

asdf8,

Consider this from the help file

Normally in a Select or Switch block, a case ends when the next Case statement is encountered. Executing the ContinueCase will tell AutoIt to stop executing the current case and start executing the next case.

You might assume that "...executing the next case..." implies evaluating the case expression, however, that is NOT true. The code in the next case stmt is executed regardless of the expression in the case stmt.

Good Luck,

kylomas

I wanted to draw attention to the illogic of conduct and the name of the operator ContinueCase.

As to my opinions, that was well add to ContinueCase optional parameter to except existing algorithm of the work, possible was check the condition in the following Case.

asdf8,

I do not find the name ContinueCase as illogical as you do, but I can see why some might.

However, I am not sure that your suggested improvement is a good idea. Switch and Select structures are normally limited to a single Case being actioned within them - I see your suggestion as making them little more than a series of independent If structures which could be quite simply coded using the current syntax. But go ahead and post a Trac ticket if you wish - the Devs will decide.

This is not a continuation of the processing of cases, this is an unconditional jump to the next case.

Apparently, due to the low productivity, AutoIt is little used for data processing, otherwise the discrepancy would have noticed long ago.

It is a pity that in this topic there was no argument from developers.

[BrewManNH]

Most people find no need to use ContinueCase at all, so that's probably why it hasn't been commented on.

[ripdad]

Good point.

Usually, a good IF Statement or series of statements within the Case will do nicely.

They rarely look in the Help sections of the forum - that is why I suggested opening a Trac ticket.
