mikroBASIC

- Basic Compiler for Microchip PIC microcontrollers

We recommend careful use of absolute directive, because you may overlap two

variables by mistake. For example:

dim Ndot as byte absolute $33

' Variable will occupy 1 byte at address $33

dim Nrem as longint absolute $30

' Variable will occupy 4 bytes at $30, $31, $32, $33,

' so changing Ndot changes Nrem highest

' byte at the same time

mikroBasic uses internal algorithm to distribute variables within RAM. If there is

a need to have variable at specific predefined address, use the directive absolute.

Also if, for some reason, you want to overlap existing variables, use the directive

absolute.

program lite

' example for P16F877A

dim image_trisa as byte absolute 133

main:

image_trisa = $ff

end.
