Program Specification Block

The program specification block (PSB) defines all of the database views that are available to an application. A PSB consists of one or more PCB definitions similar to the one shown in Figure 18. One PSB can contain up to 255 separate PCBs.

For each PCB you define, you must include the PSBGEN statement. The PSBGEN statement names the PSB and specifies the language in which the current applications are written.
