If you are getting LINESIZE errors like this:
ERROR: The width of <variable name> is not between 1 and 256.
Adjust the column width or linesize.
Then you need to issue:
ODS LISTING CLOSE;
before your job runs.
The LISTING window is limited to LINESIZE. PROC REPORT, as suggested will display longer values -- you don't need the WRAP option if you use an ODS destination like HTML, PDF or RTF.
Here's an example:

In this example, LONGVAR1 was over 1100 characters and LONGVAR2 was over 1400 characters.
