Multiple procs. Specifically, I used in PROC SGPLOT as a value label, PROC REPORT as a column header as well as a row header, PROC ODSTEXT, etc. If there are PROCs that support this kind of functionality and others that don't, I'd like to know that too.
EDIT: so, apparently, both PROC PRINT and PROC report do this correctly with text in the cells--they both break a line at the dash. PROC SGPLOT does not break at the dash when labeling values on x axis. I will need to double-check how dash is treated in PROC REPORT column headers.
