Hello Ronnie,

Any statement starting with pragma is a compiler directive. Hence in this case it depends upon compiler to compiler. It seems that you are using Metrowerks compiler, pragma DATA_SEG *** means that the variables of the below code are going to be placed in the RAM segment ***.

For detailes refer to the Metrowerks (Hiware) compiler manual.

Hope it helps
