It looks like it does actually work, but if you do certain things (e.g.
examine the output from within MapInfo after a STOP command) the column gets
blanked out.

Subject: MB SQL Select:  using variables in Select clause
Date: 25 January 1999 11:19

I'm trying to use a MapBasic variable in a select expression but I can't
seem to get the MapBasic application to pass the value of the variable over
to MapInfo.  However it works fine from the MapBasic window.

Example:

Dim i As Integer
i=1000
Select i + 2 From <table>

If I do this from the MapBasic window I get a column called _var_+2 filled
with value 1002.  Fine.  If I do it from a MapBasic application I get a
column of the same name which is blank.  Not so fine.

Help!

What I am trying to do is use a Select statement to find the maximum
distance from a given point to all the line segments in a table.

Thanks
