I get to know Pgaccess (and tcl too) now.

If you want to bound some controls to the fields of the recordset, you will
have to name their associate variable like that :

.mf.qry.salary to get the "salary" field , or .mf.qry.name to get the "name"
field.
<<<
What does it mean?
I have tried in a form:

.mf.query3:execute
set v1 [.mf.query3:fields] #-> v1=elso
set v2 ${.mf.query3.elso} #-> ".mf.query3.elso":no such variable
.mf.query3:close

What should I do?
