The SYSPROD function
returns 1 if a specific SAS software product is licensed, 0 if it
is a SAS software product but not licensed for your system, and -1
if the product name is not recognized. If SYSPROD indicates that a
product is licensed, it means that the final license expiration date
has not passed.
It is possible for a
SAS software product to exist on your system even though the product
is no longer licensed. In this case, SAS cannot access this product.
Similarly, it is possible for a product to be licensed, but not installed.
Use SYSPROD in the DATA
step, in an IML step, or in an SCL program.
