The specified TDP identifier (TPpid) must only contain characters from the standard EBCDIC character set. When DBCHCL is called for the Connect function, TDpid is obtained from the logon string if one is provided and if it contains a TDpid. If TDpid is not available from the logon string, then DBCHCL takes tdpid from Input TDP Path. If the first character of Input TDP Path is hex 00 or 40, DBCHCL obtains TDpid from MVSTDP for z/OS in the HSHSPB.

On z/OS, TDpid specifies the z/OS subsystem name, which must have the form TDPx, where x is 0‑9, A‑Z (not case specific), $, #, or @. The first three characters must be TDP.
