To use ISPF and ISPF/PDF, TSO/E users must have access to ISPF and ISPF/PDF data sets. You must modify the TSO/E logon procedure to allocate the required ISPF and ISPF/PDF data sets.

Before you modify the logon procedure, however, you must decide how users will access ISPF/PDF at your installation. To give users access, you can display the primary ISPF/PDF panel first when users log on, or display a panel that gives users access to the primary ISPF/PDF panel. For example, you could display the Information Center Facility panel as the first panel, giving users indirect access to ISPF/PDF. Instead of displaying a panel, you could simply allow users to invoke ISPF/PDF from TSO/E READY mode in response to the READY message.

In the logon procedure, use the EXEC statement to point to a CLIST or REXX exec that starts ISPF and displays either the primary ISPF/PDF panel, or a panel that gives users access to ISPF/PDF.
