First of all, your code begins with

0010 dim a[b,c]

where 'b' and 'c' are undefined (ie. they have no value).

However, you can simulate two-dimensional arrays like this:

0008 let Columns=5
0009 let Rows=4
0010 dim a[Rows*Columns]
0020 for y=1 to Rows
0030     for x=1 to Columns
0040         read a[(y-1)*Columns+x]
0050     next x
0060 next y
0070 data 0,2,3,0
0080 data 1,0,5,0
0090 data 0,4,0,1
0100 data 3,5,0,0
0110 data 4,0,0,2

(Note: this wasn't tested.)
If it doesn't work, add '-1' to line 40, before ']'. I can't remember whether NS Basic starts counting at 0 or 1. It probably doesn't let you explicitly specify the starting and ending subscripts of arrays.

(And do yourself a favor and use descriptive variable names, even though they take more time to type. They'll make things much easier.)
