VARIABLE CONTENT AS COMMAND

HI EVERYBODY.

Is ther any way to use the content of a variable as a command or reference? or create a command or macro or function?
supposing i want to store the word "TurnDo1on" in a variable named xyz and use the content of this variable in a gosub to execute block TurnDo1on: for example.

instead of writing :
GOSUB TurnDo1on

maybe something like:
GOSUB(TurnDo1on)

or:
GOSUB&TurnDo1on

Thank you.

Nothing like this is implemented in Microbasic, nor are parametric functions. You will most likely have to use a series of IF statements.
