Along with the macro use idea, a Different Approach is to build your select statement via variable and then
SELECT (the contents of the resulting variable)
cQUERYWHERE= thisform.SC1.searchexpr()
cQUERYSTATUS= Upper(SUBSTR(thisform.lstTRANS.Value,1,7))
gQUERYORDER= thisform.lstFields.Value
sqlSELECT =" * From "+ Alias()+ " Where " + cQUERYWHERE + " Into Cursor Q3"+ ;
" ORDER BY "+ Alias()+"."+ cQUERYORDER
SELECT &sqlSELECT
