Select-SQL can be extended by using UDF:
Select myfunction(filename) as result From table1

Function myfunction
Lparameter cFilename
DO CASE
....
ENDCASE
Return

However, if you're going to switch work areas you shouldn't use this way, because SELECT can get confused and yield wrong result (usually GPF :). So, for multi-table processings you probably should use SCAN. Certainly, I cannot state it by sure without knowing what exactly you want to process.
