OK here we go...!
I have got 12 variables, and i have defined each one to be an array
element -
data_store(0) = variable_1
data_store(1)=variable_2
etc
When the program is started, the array is populated by a datafile - I am not
sure of the exact sytax because i dont have my code here and i am brand new
at this language -
FOR data_store elements 1 - 11
open datafile
read in variable
close datafile
I then print the array to standard output to check that the contents match
those of the datafile. This turns out correct.
The next thing i want to do is create a textbox for each variable to accept
a new value from the user.... again excuse the lack of "correct" code-
var1 = WwTextBox(layout, "get_data_cb")
The textbox callback procedure (called "get_data_cb") needs to accept the
contents of the textbox and somehow store
this new value back into the corresponding array element - i.e if you change
the value of variable 1, data_store(0) should be amended to 1. Still
following me?
The problem i have is that i dont have the slightest clue how to make the
callback procedure differentiate between which variable it is changing,
since it is called with every textbox. I could write 10 different callbacks
but i would prefer to do it with one. I thought of using a case statement
(one case for each variable) but I couldnt get it to work. The other problem
is that I can't actually pass the value of the textbox back into the main
program to change the value of the array anyway.
Hope this makes the problem clearer...
