Hi,

Sorry if the answer is obvious but can't find anything in the manual.

Thanks

In Pro, use

#constant variablename value

The only draw back is that it replaces anything, not just values, such as:

#constant image sound
Make image from memblock 1,1

Will produce:

Make sound from memblock 1,1

You could just use global vars

Global varname = value

may wanna more strongly type your variables.
Instead of Global varname = value, use Global varname as (integer,string,float,etc) = value. So for an integer you'd say:

global intVarName as integer = 100 (or whatever value)

I usually use $ and # after the variable so I know what type it is. I guess its a matter of preference.
