#1 exception raised if more than 3276 rows in tabular data

[Anonymous]

Value error raised in xlw_opblocks.py when there are more 3276 rows of data in a sheet.

That axception is raised by chr() function (line 212 of module xlw_opblocks.py) applied to 'op' list that contains the element O1 > 255.

O1 is greather than 255 if 'offset' variable is greather than 65535 in line 210 of same module.

offset is greather then 65535 when there are more than 3276 rows in 'rs' list in xlw_maker.py line 60.
