Jan-Eric,

We all started somewhere...

This guy has said he is a newbie, and I wish him the luck in the world.

Ed, Something you may not have realised is that there are 2 very =

different ways of using MPLAB. Absolute and relocatable.

With absolute, you specify how things are done and due to this you have =

to ensure that thing are done correctly, the examples you are using may =

not have too many issues but there are pages and banks that need to be =

considered.
With relocatable, the linker does most of the work but you still have to =

take certain precautionary measures.

If you copy and paste lesson 5a into MPLAB and set up the environment =

for absolute, it should compile, by the time you get to lesson 16, the =

examples change to relocatable.

Most of my 'old' projects were written using absolute mode and do =

exactly what they were designed to do.

As Jan-Eric has stated, when using relocatable code, you do not specify =

addresses, you reserve variables and workspace and the linker does most =

of the rest for you. When using absolute mode, you specify the =

addresses. Also, when you make an error and are advised why, making the =

same error and asking for the same help can wind engineers up :-)

Cheers,

Dave (G0GMK)
