JCL and Control Statements 
Although the ACS exec can generate a template job file, the utility control statements (and 
possibly the SCP JCL) must be modified by the user. To do this the user should have some 
understanding of the format and function of these statements. 
SCP Batch Job Control Language (JCL) 
The function of the SCP Job Control Language is to provide enough information to the 
SCP to execute the requested utility within the SCP batch job environment. It defines the 
name of the job to be executed, the name of program module to execute, the specific files 
to be used by the program, and perhaps some miscellaneous parameters. 
The suggested file type is SLKJCL, and the file must consist of fixed, 80 column 
card-image records, composed of the following job control statements:
/JOB jobname pgmname
/PARM parms ... 
/COMM comments ... 
/FILE fileopts ...  
Note: With the exception of the /PARM statement values, all JCL statements are case 
insensitive.
 /JOB Statement 
The /JOB statement must be the first statement in a file of Job Control statements known 
as a job stream or JCL. It defines the name of the job (jobname), and the name of the 
program module to be executed (pgmname). Typically this is SLUADMIN. 
There must be one and only one /JOB statement per job stream.
 
jobname
the name of the job. It must be from 1 to 8 alphanumeric characters beginning with 
an alphabetic character. 
pgmname
the name of the program to be executed. It must be from 1 to 8 alphanumeric 
characters beginning with an alpha. Program must be a module in one of the 
SCP/HSC LOADLIBs.
