Mouse selection on a subfile.

Hi Chaps and chapesses,

I have a subfile where the user can select one or more records. Basically it is 
just a code for air waybills (xxx xxxx xxxx) so the subfile is displayed in 
four columns with a select field in front of each code. Now I thought it would 
make the users life easier if he/she could select the records by mouse. So the 
scenario is that the user clicks on as many records per screen as they want and 
then press enter to process them. This process is to replace the current one 
where the user has to go thru 3 screens per AWB with mucho repeatative keying 
of data.
So am I being too ambitious? I have tried using MOUBTN and PSHBTNFLD today (for 
the first time) going thru the examples and documents I can find on the net and 
in here, and they work fine, but they are for a single event, ie Enter, Exit 
etc. what I want to do is flag all the records they want and then process them 
en masse. I have tried various things but none even compile. 

Can it be done?
