I have a flat file with VB, length 4000 on mainframe.

I wrote :

data anything; infile vb; input @1 var1 $char2........ @3992 lastvar 8.; run;

I know how to convert it to FB, length 4000. My question is : for me to use Input @, do I really need to convert from VB to FB? I know if it is a CSV, it probably is a nonissue. I just set the delimiter right. I browed the VB file on mainframe. It looks messy, but the results, by proc freq, look fine. After the conversion, the data look straight columns.

Thanks. PD
