You must write a message control program (MCP) procedure for starting TSO/TCAM time sharing. Include the procedure in either SYS1.PROCLIB or in an installation-defined procedure library. In the procedure, you must include an EXEC statement and DD statements. Figure 1 is a sample procedure for starting TSO/TCAM time sharing.

//TCAM EXEC PGM=IEDQTCAM,DPRTY=(13,9) TIME=1440
//
//R5041    DD  UNIT=0A1
//         DD  UNIT=0A2
//         DD  UNIT=0A3
//L3270    DD  UNIT=01D

EXEC

identifies the MCP, IEDQTCAM, to be executed. If you omit the name of an MCP on the EXEC statement, the first MCP listed in the TST (TCAM subtask table) is attached. For more information, see TCAM Operations Guide.

If you use an MCP other than IEDQTCAM, you must specify the name of the MCP in the TCAM program properties table (PPT) and mark it nonswappable. The PPT describes the environment TCAM requires to operate properly. For more information, see .

DD

identifies the line addresses dedicated to TCAM. The ddnames must be the names identified on the DDNAME parameter of the TCAM LINEGRP macro statement used in TCAM initialization. For more information about the LINEGRP macro statement, see ACF/TCAM Version 2 Base Installation Guide.
