getd in SRC

[Easycore]

Hello,

 

It's posible use getd in SRC?

 

For eg:

 

M$ = Var

 

 

getd(""+M$+"Something") = "VarSomething".

 

 

I tried:

 

pc_readglobalreg(sd, add_str("M$"))+"Something" , but it generates map-server-crash.

 

In short, I would like to be able to "join" strings.

 

For more information, I used this in clif->soundeffectall:

 

 

clif_soundeffectall(src, (pc_readglobalreg(sd, add_str("M$"))+".wav"),0, AREA); 

 

Regards~
