Before creating new program objects, you may want to download existing program objects for the current region, to get the most recent information from the mainframe host. Use these steps:
If you click OK, CICS BAC connects to the mainframe, downloads the objects, and adds them to the Programs folder. If instead you click the Browse host button, CICS BAC connects to the mainframe and returns a list of program objects in the CICS region's control file that match the name provided. You may then select a program to be downloaded from the control file. If you haven't already specified a host user ID and password, you will be asked to enter your user ID and password to complete the connection.
