General coding rules

The general format for all ICETOOL operator statements is:

OPERATOR operand ... operand

where each operand consists of KEYWORD(parameter, parameter...) or just KEYWORD. Any number of operators can be specified and in any order.

The following rules apply for operator statements:

The operator and operands must be in uppercase EBCDIC.
The operator must be specified first.
One blank is required between the operator and the first operand.
One blank is required between operands.
Any number of blanks can be specified before or after the operator or any operand, but blanks cannot be specified anywhere else except within quoted character strings.
Parentheses must be used where shown. Commas or semicolons must be used where commas are shown.
Operands can be in any order.
Columns 1-72 are scanned; columns 73-80 are ignored.
Continuation can be indicated by a hyphen (-) after the operator or after any operand. The next operand must then be specified on the next line. For example:
```
SORT FROM(INDD) -
   USING(ABCD) -
   TO(OUTPUT1,OUTPUT2,OUTPUT3)
```
Any characters specified after the hyphen are ignored. Each operand must be completely specified on one line.

A statement with an asterisk (*) in column 1 is treated as a comment statement. It is printed with the other ICETOOL statements, but otherwise not processed. A statement with blanks in columns 1 through 72 is treated as a blank statement. It is ignored, because ICETOOL prints blank lines where appropriate.
