Running an application under TSO

Before you run your program under TSO, you must have access to the runtime library CEE.SCEERUN. To ensure that you have access to the runtime library, do one of the following:
The TSO CALL command runs a load module under TSO. If data-set-name is the partitioned data set member that holds the load module, the command to load and run a specified load module is:
CALL 'data-set-name' ['parameter-string'];
For example, if the load module is stored in partitioned data set member SAMPLE.CPGM.LOAD(TRICKS), and the default runtime options are in effect, run your program as follows:
CALL 'SAMPLE.CPGM.LOAD(TRICKS)'

If you specify the unqualified name of the data set, the system assumes the descriptive qualifier LOAD. If you do not specify a member name, the system assumes the name TEMPNAME.

You do not need to use the CALL command if the STEPLIB ddname includes the data set that contains your program. For example, you could call a program PROG1 with two required parameters PARM1 and PARM2 from the command line:
PROG1 PARM1 PARM2
