[Dxspider-support] SHOW/DX with exact match ?

Mon May 12 18:23:02 BST 2008

Hello Robert (and Dirk)

how about using the standard symbol keys (used as example in linux)?

Something like

SH/DX HB2008G   = search the exact call
SH/DX HB2008*  = search all HB2008* calls
SH/DX HB9DH?    = search all calls that have 1 letter after HB9DH
SH/DX HB9?HG    = easy ;) ?

Just a suggestion ;-)

Regards,

Hi Dirk,

Many thanks for your answer!

I didn't suggest to make my proposal the default behaviour of the SHOW/DX 
command, but just to add a parameter which would mean that only exact
matches 
are wanted.
For exemple, something like "SHOW/DX =call" or "SHOW/DX EXACT call"
which would be used only by those who know about this option and need it in
a 
particular situation.

How about this ?
