(...) Lego's usage of the terms'local' and 'global' is a little different than what most people expect. In the RCX, global storage is available across all tasks while local storage is avaialble per task. This is different from the more traditional (...)

(...) Remember that the RCX has no stack or heap. This means that, effectively, there is no memory pool from which to allocate things. Here, 'local' means belonging to the current task not the current function, and the number of tasks is fixed (at (...) (23 years ago, 20-Feb-02, to lugnet.robotics.rcx.nqc)

Hi John, (...) Yes ! Using more tasks you will get more local space (for each task 16). So maximum number of variables is 32+(16*10) = 192 (...) That's how NQC is handling memory for local variables in functions, subroutines, tasks. Local has a (...) (23 years ago, 20-Feb-02, to lugnet.robotics.rcx.nqc)

Global variables are obviously always allocated in one of the 32 global storage (...) (23 years ago, 20-Feb-02, to lugnet.robotics.rcx.nqc)

When using the RCX2 target, the NQC manual (Section 2.2.4) states that 32 global variables, and 16 local variables (per task) are allowed. Does this mean that the whole program can only have 48 variables total when using only one task, ie. "main" , (...) (23 years ago, 20-Feb-02, to lugnet.robotics.rcx.nqc)

(...) Yes that's exactly what I'm trying to say !! To day I had an even stranger experiences: 1. the size of BricxCC became smaller after opening the first file, still depending on the size (or is it the content) of the file 2. in one of the tests I (...)

Have I understood your description of the problem correctly? Are you saying (...) (23 years ago, 19-Feb-02, to lugnet.robotics.rcx.nqc)

hi John, thanks for your attention. I know the cause, you know the solution ;-) The size of BricxCC when opening the first file, depends on the SIZE of the file to be opened. 8 bytes, window stays as it is 256 bytes, blows the window up to about (...)
