Hello Alan

#pragma rambank locates VARIABLES ONLY in the required rambank. To assign functions to a given page use #pragma codepage (see
page 43 of manual).

I prefer to use the following syntax for placing functions and variables:

variables --  bank0 uns8 var_name;
functions --  page0 void function_name (void);

I can see straight away where they are located, and to build a header file to include in other modules I just copy and paste the
prototypes putting 'extern' in front of them all.

Hope this helps.

Steve
