Use variable in the variable

Stevegiovanazzi · Jan 6th 2023

Hi Everyone, i'm trying to make something maybe it's not possible.

I need to use a value of an interger var to recall different var.

the situation now :

-SetUserVar SG_NUM 1
-SetUserVar SG_ADDVAR "SetUserVar SG_NUM 1$SG_NUM"
-Label Page $SG_NUM $"SG_Song_1" ; Label Sequence $SG_NUM $"SG_Song_1" ;Label Macro 101 $"SG_Song_1" ; $SG_ADDVAR
-Label Page $SG_NUM $"SG_Song_2" ; Label Sequence $SG_NUM $"SG_Song_2" ;Label Macro 102 $"SG_Song_2" ; $SG_ADDVAR

ect...

I want make the recall of the VARIABLE SG_Song_x based on the SG_NUM that is incremental for every row.

It's possible recall i var that is made from an value of another var?

Something around this i think:
Label Page $SG_NUM $"SG_Song_"$SG_NUM

To me this seems to be much easier with a simple plugin. If I read your macro code well, you want to label a series of pages, sequences and macros with the name "SG_Song_x". To achieve this you can use something like this:

Code

local labelsongs=function ()
    local i_startsong=tonumber(TextInput('First songnumber','1'))
    local i_lastsong=tonumber(TextInput('Last songnumber','2'))
    for i_song=i_startsong,i_lastsong do
        Cmd('Label Page %d "SG_Song_%d"',i_song,i_song)
        Cmd('Label Sequence %d "SG_Song_%d"',i_song,i_song)
        Cmd('Label Macro %d "SG_Song_%d"',i_song+100,i_song)
    end
end

return labelsongs

Of course, you can extend this plugin so that you can set other parameters such as the base song name, the start page, start sequence and start macro.
