Program works in real, not virtual

[roadrunner]

The only document I know of on running CAS commands from PPL other than the users manual is here:

https://www.hpmuseum.org/forum/attachment.php?aid=3547

It may be somewhat outdated with with the current update though. Generally, if you want to run a CAS command from a PPL program you have to use this format:

CAS(EVAL("a string exactly like what you would type on the CAS command line"))

I don't think that's always required so you have to experiment to find the best method for any particular application.
