if you don't need the tables in qvw-file and your goal is to create qvds out of txt files you could even loop over all the files like this:
For each vTableName in 'Table1', 'Table2', 'Table3'
Load * From $(vTableName).txt
(txt, codepage is 1252, embedded labels, delimiter is ',', msq);
Store $(vTableName) into $(vTableName).qvd (qvd);
Drop Table $(vTableName);
The filelist for the loop could also be dynamically created via the filelist() function.
Hope this helps
