The following rules apply to the creation of IEFSSNxx:
- Each SUBSYS statement in IEFSSNxx defines one subsystem to be
initialized.
- Use columns 1 through 71. Do not use columns 72-80, because the
system ignores these columns.
- Comments may appear in columns 1-71 and must begin with "/*" and
end with "*/".
- A statement must begin with a valid statement type followed by
at least one blank or end-of-line. If there is an error in the statement
type, the system will flag the error on the preceding statement.
- A statement ends with the beginning of the next valid statement
type or end-of-file. Therefore, if there is an error in a statement
type, the system will flag the error on the preceding statement.
- A statement can be continued even though there is no explicit
continuation character. Be aware that if the system cannot recognize
the start of a statement (for example, if a statement starts with
an error in the statement type), the system will automatically assume
that it is a continuation of the previous statement, and flag an error
on the previous statement.
- Operands must be separated by valid delimiters. Valid delimiters
are a blank, or column 71. If the operand contains parentheses, then
the right parenthesis is accepted as a valid delimiter.
- Multiple occurrences of a delimiter (except for parentheses) are
accepted, but treated as one.
