Writing required JCL statements

An ICETOOL job consists of:

The JCL statements that are required for every ICETOOL job.
The operator statements indicating the operations to be performed by the ICETOOL job.
The JCL statements that are required as a result of the specified operator statements.

The first step in creating any ICETOOL job is to write the JCL that is always required. Here is a skeleton of the JCL for an ICETOOL job:

//EXAMP    JOB   A492,PROGRAMMER
//TOOL     EXEC  PGM=ICETOOL
//TOOLMSG  DD    SYSOUT=A
//DFSMSG   DD    SYSOUT=A
//TOOLIN   DD    *
  <ICETOOL statements go here>
/*
<Additional JCL statements go here>

The JOB statement signals the beginning of the job.
The EXEC statement signals the beginning of the job step and tells the operating system to run the ICETOOL program.
The TOOLMSG statement defines the output data set for ICETOOL messages.
The DFSMSG statement defines the output data set for DFSORT messages.
The TOOLIN statement precedes the ICETOOL statements (comment, blank, and operator statements). The ICETOOL statements you write must appear after TOOLIN. The additional JCL statements you write can appear before the TOOLIN statement or after the ICETOOL statements. In the main ICETOOL job, the additional JCL statements will be placed after the ICETOOL statements.
