wrapit5.pl -- Wrap Fixed-Format Variable Statements

---

This Perl script reads a file containing a column of SAS Input or SPSS Data List statements and reformats them into a wrapped format with multiple fields per line--defaulting to five columns wide. Handy for making long, single-column declarations more compact and readable in your code.

• Output is sent to STDOUT, so redirect it to a file to save it.
• Output is five fields per line, using fixed-width spacing for readability.
• Developed for quick formatting of variable lists during SAS/SPSS prep, especially when transforming the output from splitit.
