Append data to the end of each row

Hello all,

I have a delimited input file with close to 100 fields. i would like to append data to the end of each row. But i don't want to define each of the 100 fields in the input section. in addition, since it's a delimited file, each row has different length. Is there a way to skip to the end of each row from an input file when reading it?

Thanks for any input!

Re: Append data to the end of each row

Using a DATA step, it is possible to read up the current data record using an INFILE and INPUT statement, and then address it with the SAS reserved variable _INFILE_ for whatever purpose you might require. A very simple SAS DATA step is listed below for your review/consideration.

Also, the INFILE statement has parameters you can code to identify the record length, current column pointer location -- review the SAS Language INFILE discussion for details.

Or you could skip n fields by reading past them:
input var1-varn $ @;
drop var:;
