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, Ga… [more]

All, I was hoping someone might be able to help me understand a problem I'm having calling sac within a perl script, and using a 'foreach' loop to edit a list of files. When I run the following script on a linux machine (running sac2000, version 00.59.48), it runs fine and exits without problems. When I run the same script on an Intel macPro (running sac version 101.0), the script hangs within the foreach loop after processing the last file in the list and does not exit sac. … [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.
