It is recommended that DK1TCALL be statically linked, and not defined to CICS. By statically linking DK1TCALL, the PPT is not searched for DK1TCALL and the call is very efficient. If it is called dynamically, it must be defined to CICS.
All other tableBASE modules are loaded and kept resident under CICS; a single copy serves all users.
DK1TCALL is supported under the CEDF transaction allowing tableBASE calls to be traced and debugged.
