Strange warnings when compiling

[mytekcontrols]

I get the following Warnings, but this is followed by a "Success", and then proceeds to program the PIC16F877a without any problems. Basically the code seems to work just fine in my application, but the warnings do concern me.

Any ideas as to what this means, and can I simply ignore the warnings?

I am running version 3.22 on an XP Home machine with the latest windows updates.

Yes, you can ignore the warnings headed with 'Warning unreferenced functions removed:'.

Each component loaded onto a Flowcode flowchart provides the resulting program with a complete set of its functions.

When the program is compiled it is analised by an optimiser that removes any functions that were loaded but not used. Most Flowcode progams will generate several of these warnings.

The resulting code receives further adjustments to improve efficiency before the final .asm and .hex files are generated.

The warnings would be a possible source of debugging information for a faulty program if a function you knew to be required appeared in the list.

Cool
Thanks for the quick answer Sean.

I was hoping that it was unimportant, and you confirmed it.
