As of Version 6:
- no TBTSLIB is required
- there is no need for various TBROOTIx (where x is a digit) modules; TSR size is determined by a site-configurable default or by parameter input through the TBOPT initialization file
- the equivalent of the Release 5.X TBROOTI module in the current release is DK1TROTB which is reentrant and resides above the line
- the tableBASE Program Call (PC) Server is required.
