Hi FelicityV, I'm with Stuart on this, what are you trying to do with your SCL? Is it batch ADMIN SCL and DEFINE TYPE and trying set values for base/delta/source output type libraries that include site symbols, or perhaps DEFINE PROCESSOR SYMBOL... Without the context of what you are trying to do it's hard to help.
Even though you've opened a case with support, now that you've got the community interested it would be helpful to share a little more information.
