understanding the data from the ucsc table browser

im trying to find the intron length distribution of the hg18 assembly downloaded from the table browser.the refseq file has the following columns in iti calculated gene length by txstart-txend and made a plot of the distribution..however i need to find the intron length .

"bin" "name" "chrom" "strand" "txStart" "txEnd" "cdsStart" "cdsEnd" "exonCount" "exonStarts" "exonEnds" "score" "name2" "cdsStartStat" "cdsEndStat" "exonFrames"

length of ith intron:

intronLength +=  $exonStarts[ith+1] -  $exonEnds[ith]  )
