Chris, I'm not sure why NQC would offer arrays and the scripting language
wouldn't. I am certainly not the resident programming expert:) Anyway, I can
send you some code when I get home. I copied the following directly from the
NQC documentation:
2.2.5 Arrays
The RCX2 target supports arrays (the other targets do not have suitable
support in firmware for arrays). Arrays are declared the same way as
ordinary variables, but with the size of the array enclosed in brackets. The
size must be a constant.
int my_array[3] ; / / declare an array with three elements
The elements of an array are identified by their position within the array
(called an index). The first element has an index of 0, the second has index
1, etc. For example:
my_array[0] = 123 ; // set first element to 123
Currently there are a number of limitations on how arrays can be used. These
limitations
will likely be removed in future versions of NQC:
•An array cannot be an argument to a function. An individual array element,
however, can be passed to a function.
• Neither arrays nor their elements can be used with the increment (++) or
decrement (--) operators.
•Only ordinary assignment (=) is allowed for array elements. The math
assignments (i.e. +=) are not allowed.
• The initial values for an array's elements cannot be specified - an explicit
assignment is required within the program itself to set the value of an element.
Hope this helps,
Rob

ROB, you are the best.!!!!!! this bit of documentation was all the answer i needed. thank you!!! its a shame that you have to use a constant to assign the array. :( BUt this is better than nothing.
