The TBCREATE service creates a new table in virtual storage, and opens it for processing.
TBCREATE allows specification of the variable names that correspond to columns in the table. These variables will be stored in each row of the table. Additional "extension" variables can be specified for a particular row when the row is written to the table.
One or more variables can be defined as keys for accessing the table. If no keys are defined, only the current row pointer can be used for update operations.
