You have SAS-standard NLS (National Language Support) formats which address the decimal/comma consideration. You will need to look in the SAS National Language Support (NLS): Reference Guide for details, however I provided a DOC link below which mentions them.
Or, the PICTURE statement you have shown can also be changed from a comma to a period.
