Hi,
that 's right, global variables could be displayed but not the local ones.
Therefore I 've another test file which uses a global variable i and a
local variable k.
If you run the program on your rcx you would see first the global i that
is 100.
After this there should be displayed the local variable k that is 50.
But there
is the mistake. You see the global i and not the local k. The third value
should be the global i .. is 200 and is okay. And the last one should be 300.
Dave wrote that locals can't be displayed. I 've tested this and it
seems
so but I don't know why

| (...) Lego's concept of 'local' variables are variables that are context swapped per task, as opposed to the normal variables that are not context swapped (all tasks share the same vars). Thus, 'local' RCX variables are local to the task. This is a (...) (25 years ago, 8-May-00, to lugnet.robotics.rcx.nqc)
