This is probably a simple question.  I have a table which is not mappable
which contains a list of about 300 (1:250 000) grid numbers (ie: 011L
etc...).
I do not have a digital 1:250 000 grid layer (for all of Canada). Does
anyone know where I can download a 1:250 000 NTS grid for all of Canada?

I do have a digital 1:50 000 grid file which contains 11000 records (grid
regions). Each record contains the grid number (ie: 011L11 etc...)
What would be the easiest was to select all the 1:50 000 grid regions that
correspond to my list of 1:250 000 grids that is listed in my non-mappable
table?
Somehow I have to search and select the records in the 1:50k table in which
the first three grid numbers match the 1:250k numbers listed in the second
table.

Or would it be easier to create a digital 1:250k mappable grid table from
the 1:50k that I already have? If so, how?

I have MI 6.5 but do not have MapBasic.

TIA

Dan
