Hi all, I've seen similar messages with problems using blackboard variables on the newest version (101.0) of sac in the mailing list threads, but no replies. Sorry if this is a repeat. When I try and evaluate straightforward math using the blackboard variables on a Intel MacPro (see below), my answers are wrong (although no error is reported). The same commands work fine on previous versions of sac. Has anyone come across a similar error, and/or know of a fix? Thanks much, ... [more]

Hi Oscar, I'm not sure I understood your question. Read your signals and Call sss subroutine, there you can stack them, to do it they have to Have the same time step. The manual of sss your guide along the different Options you can use.

Hi Ken, Normally you dont need to copy the sacio.a library, you only have to Specify in your Makefile the place where the library can be found.
