when here:
(1) what does Dynamic & Static really mean ?
(2) what the purpose of moving the slider in one direction
or the other?
Dynamic/Static
Dynamic/Static
Thank You for your help

Hi,
http://www.mikroe.com/forum/viewtopic.php?t=11316
The microchip 16bit CPUs have multiprogramming capabilities using the classical CPU stack architecture. Whenever an user subroutine is called or an interrupt subroutine is triggered, the CPU saves the current context registers to the stack (which uses RAM). With multiple level and multiple interrupt subroutine capability, the stack RAM requirement is dynamic and could be substantial, depending on your program. In addition, your local subroutine variables are created dynamically and stored in stack data space, and released upon subroutine exit. The CPU has a stack pointer to keep track of the dynamic stack requirement, and the maximum data memory that the stack pointer can use is set by the SPLIM register which is set by you using the slider in the Edit>Project menu.
So!
1. The mikroE default is to divide all available data RAM into two halves, one half of RAM for your global program variables, and the other half for dynamic subroutine variables and context registers.
2. If you have a rather large main program and do not have a lot of multiple level subroutines / interrupts with large local variables, you can possibly try 80% static / 20% dynamic allocation, giving yourself more RAM space for global variables.
3. If your global variables require say 25% of RAM, and ost of your processing is in interrupt and user subroutines with lots of local data, you may want to try 30% static / 70% dynamic allocation.

Thank you for explaining about the slider ,I am aware of the static and dynamic situation in C30 where you set it in the compiler options but did not know you can do this in mikroBasic by ajusting the slider
Great ,I start to like the Basic compiler just hope we will get the pro verion soon !!
