Yes it is SAS 8. It is referenced, for example in the PDF version of the
CD-ROM
documentation drive:\SASV8\Documentation\PDF\saspdf\lgref\pdfidx.htm in the
SAS Language Reference: Dictionary, Chapter 4, 'Functions and CALL Routines'
under 'CONSTANT' (PAGE 298). Your path name may differ.
   There are other, more machine-oriented constants also, such as
the largest double-precision floating point number (8-bytes) that is
representable on your computer.
        Other functions and calls include a function to compute combinations
of n elements taken r at a time; a function to compute a factorial; a
function
for calculating permutations, all in base SAS. And there is more.

Eric

Eric,

I tried using this function "constant" in version 6.12 and did not work.
SAS does not recognize this as a function.

Is this something new in version 8??

If so, then I understand why it didn't work.

Thanks,
Charles Patridge
