You need the variable to be a GLobal variable to be read inside of a function e.g.



or you could pass the name$ in as a parameter e.g.



Hope this helps,

jasuk70, I think you gave him the correct code but I think he needs explanation. the reason why the name does not show up is because it was declared outside of the function. A function sort of resets all variables and uses it's own, to make the function not doing this you have to use the GLOBAL command in the beginning of your code. what does the global command do? well it makes sure the variable you specified is used everywhere, so also in the functions. hope I helped

The L is also trying to be used in the Function. Did you try passing the L through as well?

FUNCTION uline$(string$,L)

I've not used Classic so this is a shot in the dark.
