is there a way of getting complier information out of RobotC? by complier information i mean like how much resources will be used by the program

Having the source compiled you can switch to the "disassembly" view where you can see the bytecode dump together with the relative addresses --> last address is approximately size of the program.

Memory consumption of static variables can be estimated by yourself (e.g. an integer array with a size of of 20x100 occupies approx 4 kbyte). Temporary variable usage is insignificant, compared to program store and static variables.

ROBOTC has quite a nice display of "Compile Statistics" that has been disabled for all but the internal debugging environment. I've just added a check box in the "Compiler" tab for "Preferences" that can be used to enable this display. It's about 10 to 15 lines of display that is added to the "Errors" window on every compile. It does include the number of variables allocated, total code space required, etc.

It's an option because very few users will be interested in this info.

thats great news dick . Question though is that in 1.40PC2 or in a later version as i can't seem to find any option in preferences and im running PC2

It is in version 1.41 which has not yet been released. Should be available in next couple of weeks.
