Do not know about SAS on VMS but here on CMS Version 5 made a change to the graphics drivers. In previous versions, a record ended with a 'graphics' off command. In version 5, on CMS the records in the file are 255 characters each and there is no 'off graphics' character at the end of the record. Hence when you have something send those records to an output device the 'END-OF-RECORD' gets sent which is strictly not part of the graphics stream. SAS has told us, and I have not fully tested, that PROMPTCHARS in OPTION will rectify. Set the third byte from a '00' to '01' which is supposed to make logical records end with a graphics off. E.G. promptchars='xxxxxxxxxxxxxxxxxxxxxx'x option; do proc options to see current setting which has 3rd byte '00'x change to '01'x
