[Dxbase] adding another call to 2006

[Alan Leith]

I keep a VE1AL.mdf that contains the QSOs made even before I had the call
and it has moved with me all over eastern Canada.  However, I see, in
preparing to upload my logs to LoTW, that I had forgotten about CK1AL and
VE1RAC which are also logged under VE1AL.

I have tried to add these calls in the options but I get a message that
there is too much information already there and no more can fit.  I am
using DXbase 2006

Is it possible to expand the line for callsigns?

Al, VE1AL

For the interest of anyone who might be able to help, I have operated under
the following calls: CG1B, CJ1AL, CK1AL, VC3FRA, VE1AL, VE1AL/3, VE1JN,
VE1JN/2, VE1RAC, VE3FRA. VE3VX, VF1L, XL1AL and XN3FRA.  This is,
unfortunately, too much for the optional call entry to handle.
