The way to do this is to find out the variable number assigned by NQC to your
array variable and then watch that variable number plus all the ones up through
the size of your array. You can find out the variable number by viewing the
code listing (F12) after you compile your program in BricxCC. At the top of the
listing will be a section which maps variable names to their assigned numeric
value.
Here's a sample program:
int aaa;
int bbb,ccc;
int values[10];
task main()
{
aaa = 10;
bbb = 20 * 5;
ccc = bbb;
ccc /= aaa;
ccc -= 5;
aaa = 10 * (ccc + 3);
values[0] = aaa;
values[1] = bbb;
values[2] = aaa*bbb;
values[3] = ccc;
}
And here is its listing:
*** Var 0 = aaa
*** Var 1 = bbb
*** Var 2 = ccc
*** Var 3 = values
*** Task 0 = main, size: 76 bytes
000 pwr ABC, 7 13 07 02 07
004 dir ABC, Fwd e1 87
006 setv var[0], 10 14 00 02 0a 00
011 setv var[1], 100 14 01 02 64 00
016 setv var[2], var[1] 14 02 00 01 00
021 divv var[2], var[0] 44 02 00 00 00
026 subv var[2], 5 34 02 02 05 00
031 setv var[0], 10 14 00 02 0a 00
036 setv var[47], var[2] 14 2f 00 02 00
041 sumv var[47], 3 24 2f 02 03 00
046 mulv var[0], var[47] 54 00 00 2f 00
051 setv var[3], var[0] 14 03 00 00 00
056 setv var[4], var[1] 14 04 00 01 00
061 setv var[5], var[0] 14 05 00 00 00
066 mulv var[5], var[1] 54 05 00 01 00
071 setv var[6], var[2] 14 06 00 02 00
Total size: 76 bytes
You would want to watch variables 3 - 12 in order to watch all 10 elements in
the values array.

| I have a program (RCX2 target) that uses a couple of global arrays. I am using BricxCC 3.3 How can I view the contents of the array at run time? "Watch the Brick" shows me Var0 to Var 31 but these don't seem to relate/contain the values I initially (...) (18 years ago, 17-Aug-06, to lugnet.robotics.rcx.nqc)
