I recently had the need to execute 2 functions with the same parameters but different behave depending on some variable data.

At first I started with a natural
[code=thinbasic]IF MyVar = 1 THEN
MyFunction_A(Var1, Var2, Var3)
MyFunction_B(Var1, Var2, Var3)
END IF[/code]

but later I remembered that CALL keyword can be used to execute a function whose name is computed as sting expression. So the above code can be changed to:
CALL "MyFunction_" & IIF$(MyVar = 1, "A", "B") (Var1, Var2, Var3)

Maybe CALL method is more cryptic but can save some code in special situation, and because scripts are parsed and interpreted, saving code means saving execution time.
