Using the TB-PARM Communication Area

DataKinetics recommends using a TB-PARM Communication Area on every call to TBLBASE. If a TB-PARM is not used, performance can be significantly affected in some instances—for example, when DK1TCALL or DK1TROTB is in LPA or an authorized library. See Batch/IMS Performance Degradation with Dynamic Calls to tableBASE.
