KB1019: Can I modify a variable using a template?
When working with Templates there are two types of variables
and it is important to understand the difference between the two.
Firstly there are Template variables which are defined in a template
using the regular C syntax, for example:
However, these variables do not behave exactly like C variables.
Templates variables are mapped to bytes in a binary file so that reading
the value of 'a' reads data from a file and assigning to 'a' writes data
to a file. Since Templates are meant to be read-only for a file these
type of variables cannot be assigned in the Template but they
can be assigned in a script. For example, in a script you can execute:
a = 5;
and this will modify bytes in your binary file. (Note that there is
nothing special you need to include in your script to access the
variables defined in a Template, as long as you run your Script
after the Template you should be able to access all the Template
The second type of variables in a Template are local variables.
These variables behave just like regular C variables and can be
assigned like normal. Local variables are defined using the 'local' keyword:
local int i;
for( i = 0; i < 4; i++ )
If you are trying to assign to a variable in a Template, make sure the variable is
declared with the 'local' keyword.
