This token should not be used for any purpose that could be accomplished by a PL/I statement.
On z/OS, the token holds the address of the DCB associated with a RECORD or STREAM file or of the ACB associated with a VSAM RECORD file. The token is not valid for other files.
Note: The DCB or ACB address is provided so that applications can
read the DCB or ACB. The DCB and ACB must not be altered.
The ERROR condition with oncode 1010 is raised when the file is not open.
