You should be able to get this to work by adding the following to your =
proces START command.=20

ENV TDI_SAS_HOME=3D{TDI_SAS_HOME}=20

In order to set an OS variable (which we usually refer to as an =
environment variable) when STARTing a process, you must specify it with =
the ENV option (note that you can have multiple ENV options).  The =
option I specified above says to set the environment variable =
TDI_SAS_HOME to the value of the STAF variable of the same name.=20
