I'm having a hard time getting to the bottom of this:
Is there any way to call a function once per set of values and then call it again only when the set of values has changed?

I have this ini. file structured like this:

VB

1_Type=012
1_Name=VOLVO
1_PDIcfgPath=D:\Work\Scanner\

2_Type=013
2_Name=VOLVO
2_PDIcfgPath=D:\Work\Scanner\

etc...

and I have a function PDIinit function that initializez the config file from the give path in the ini file (1_PDIcfgPath).
I want this function to be called only for the products that belong to one type and only if the product type is changed I want it to be called and initialize the config file for the products of that type.
Now when I call this function it initializes all the config files for every type and I want it to initialize only the config for specific type.

As with anything you need to write some decision code. Create a function that does type specific initialization and then you can call it for every type or one specific one as required. alternatively you could use a parameter which is the 'type', a string or value, and use some specific value which means select all types.
