hello everyone,

this will probably be an easy question for all you experts out there but its
got me beat -

I have been given a PV-WAVE program that simulates a certain lab experiment.
The variables for this sim
are defined in the source code and my mission is to add a user interface
using PV-WAVE widgets that allows a user to change these variables on screen
before running the simulation.

I have defined text widgets and windows and that all works fine, but i have
the following problem -

there is an array, data_store, that has 10 elements (each element represents
a variable) and this array is populated by a datafile (of "default"
settings) when i run my program. The problem is that I want the textbox
callback procedure to update the array as the values are changed by the user
on screen and I cant do it...! This then needs to be linked to the
simulation code but that is no problem. It is just the updating I can't do
right

I tried passing values between the main procedure and the callback but i
couldnt get any joy

anyone got any tips or ideas?

thanks

andy
