switch case construct
Hello !
I want to realise a switch-case equivalent.

For example while looping I read a variable from an ini file

ReadIniStr $LABEL .....
Each time $LABEL is differnt depending on my loop variable(counter)
Then I want to go to that label.
But a

goto $LABEL

does not make it.

How can I realise this ? What did I miss ?

thanks in advance

Have you checked out the 'LogicLib.nsh' included in NSIS. I think that it has a case function.

Try with something like this

#switch start


>label_case_1:

>StrCmp $LABEL "1" +1 label_case_2

>#code for "1" here

>goto label_endswitch


label_case_2:

>StrCmp $LABEL "2" +1 label_case_3

>#code for "2" here

>goto label_endswitch


>...

...


>label_case_N:

>StrCmp $LABEL "N" +1 label_default

>#code for "N" here

>goto label_endswitch


label_default:

>#default code here


>label_endswitch:

>#switch end

You only need to change the label's names if you want.

Thanks for LogicLib.nsh ! That is exactly what I need ! What a pity that it is hide in the example dir !
