To remove Carriage Return and/or Linefeed characters

Couple days ago, one of my programs, which used to compare two sets of SAS datasets, gave me warnings with discrepancies found. I checked the data manually, and figured out that the issues were because of one set of SAS datasets containing CR/LF characters.

I did use function STRIP to remove extra blank chars. I thought that SAS functions, like STRIP, TRIM, CATS, etc., could remove blank characters, like space or CR/LF. Actually, they are not.

Since CR is '0D'x, and LF is '0A'x, there are at least two functions that will do the job.
1) compress(source_text, '0D0A'x);
2) prxchange('s/(\n|\r)//', -1, source_text);
