If you only need one array, why not just create that statically (personally I
prefer the [table] object for data, I don't need to see), then load its content
with "read"/"write" messages?


 [table MyArray 100]

 [read /tmp/data1.txt(
 [s MyArray]

 [read /tmp/data2.txt(
 [s MyArray]


The textfiles should just contain the array contents, one number per line. Check out the 
file 15.array.pd and 16.more.arrays.pd in the docs for more on table manipulation.
