If it's yellow let it mellow. If it's brown flush it down.

anything that has a global element in a function

arrays declared at the top of the main
Typed arrays decalred at the top of the main


will allow u to return more than one parameter and these options dont have to be in the parameter defines for them to work, in fact only a TYPED array can be used as a parameter inside a functions parameters.

It doesnt actually return the value fromt he return area.
the arrays and or typed arrays just get updated in the functio and return there result.

If u want u could always try and break downt he function into seperate calls if u really need to return it in a true sense.

u can use normal strings floats integers etc..

see attached code snippet.

the typed array and the glob array dont need to have return parameters because they are global inside and out of functions if declared outside int he main

DBP only

but u can access arrays just the same in classic

and u need to use darkedit if using classic to utilise a form of types that get converted to arrays at compile time.
