What are the rules employed while naming the steps in a job?

There are a set of predefined rules followed while naming the steps in a job. These rules include the following:

• The steps should be purely meaningful, real and unique. This rule is crucial as different systems identify the job based on this rule.
• The step name must be coded only after the symbol “//” with no space in between
• The step name should follow after the job statement has been completely declared
• A particular job can have many steps, however, all the names must be different
• The step name should be followed after a blank space
• The step name can contain all alphabets, all numbers and the following symbols #, @ and $
• The first character of the step name should be a symbol or an alphabet
