awk to parse current and next row in tab-delimited file

Hi there,

I would like to use awk to reformat a tab-delimited file containing three columns as follows:
Data file:
Code:
sample    1    173
sample    269    530
sample    687    733
sample    1699 1779

Desired output file:

Code:
sample 174..265, 531..686, 734..1698

I need the value in the third column +1 to be paired with the next value in the second column -1, and so on. The resultant output would be a single line containing the name of the first column followed by a space and then the parsed paired coordinates.

Thank you very much for your help!
