- Interesting coincedence. I'm getting ready to release a library that has
- an 030 and a vanilla version. We're not doing anything with the math
- libraries, however.
-
- What I found is that the code for the 020, 030, and 040 were all
- identical when compiled with SAS/C 6.55. I even went as far as to DIFF
- the files to find differences other than size, and the only part that was
- different was the compile time embedded in the library's version.
-
- I can't give you a difinitive answer, but in the end we went with two
- versions of the library, one for >= 020 and the other for <= 010.
