array of array max length?

[tbone654]

I'm trying to put something in that 11th column. Which I seem unable to do.

2012/10/05 146.91 147.16 145.70 146.14  124311600   ss 0.83 0.30 0.00
2012/10/08 145.60 146.12 145.31 145.64  124842100 B  B 0.36 0.41 0.00
2012/10/09 145.53 145.65 144.15 144.20   78415400    S 0.92 0.03 0.00
2012/10/10 144.18 144.32 143.09 143.28  148872900   ss 0.89 0.15 0.00
2012/10/11 144.28 144.49 143.33 143.36  124247500    B 0.82 0.03 0.00
2012/10/12 143.46 143.95 142.58 142.89  123601500    S 0.64 0.23 0.00
2012/10/15 143.23 144.23 142.77 144.08  124181900   ss 0.32 0.90 0.00
2012/10/16 144.76 145.64 144.66 145.54  107689100    B 0.10 0.90 0.00
2012/10/17 145.64 146.32 145.42 146.20  108815500    S 0.24 0.87 0.00
2012/10/18 145.82 146.52 145.33 145.82  128834100   ss 0.41 0.41 0.00
2012/10/19 145.55 145.56 143.05 143.39  148108500 B  B 1.00 0.14 0.00
2012/10/22 143.15 143.67 142.28 143.41  185645200    S 0.63 0.81 0.00
2012/10/23 141.86 142.06 140.83 141.42  125578600 B  B 0.84 0.48 0.00
2012/10/24 141.93 142.10 140.80 141.02  192056300    S 0.87 0.17 0.00

So on a hunch I comment out the code that populates the 10th column, and guess what? Now that calc appears in the 10th column.

2012/10/17 145.64 146.32 145.42 146.20  108815500    S 0.24 0.22 0.00

2012/10/19 145.55 145.56 143.05 143.39  148108500 B  B 1.00 3.47 0.00
2012/10/22 143.15 143.67 142.28 143.41  185645200    S 0.63 3.28 0.00
2012/10/23 141.86 142.06 140.83 141.42  125578600 B  B 0.84 2.84 0.00
2012/10/24 141.93 142.10 140.80 141.02  192056300    S 0.87 1.26 0.00

Q- Is there a limit on the length of an array of arrays? Is it 10? Here's the printf

printf("%10s %.2f %.2f %.2f %.2f %10d %1s %2s %00.2f %00.2f %00.2f\n", $filename[$row][0], $filename[$row][1], $filename[$row][2], $filename[$row][3], $filename[$row][4], $filename[$row-1][5], $filename[$row][6], $filename[$row][7], $filename[$row][8], $filename[$row][9]), $filename[$row][10] ;
