• Command keyword
• One or more command parameters
• Parameter options
• Comments, if appropriate
In addition, there are syntax rules you must use in order for the system to recognize and
process your JSLs. These rules are described later in this section.
Identifier
If the command is to be referenced by another command, an identifier must precede the
command keyword.
The XDL command below has a command identifier (VFU1), a command keyword (VFU),
and three command parameters (ASSIGN, TOF, BOF):
A command identifier is a label that may consist of one to six characters (A-Z and 0-9). It
must be followed by a colon (:). The identifier VFU1 in the command above could be coded
with any number of blanks following the VFU1 characters, but no blanks within the identifier
name.
Note: A command that requires an identifier must always be defined prior to any reference
to it.
Command keyword
A command keyword is required. For example, CME is the command keyword and VFU,
TABLE, CRITERIA, CME, PDE, and so on. A command keyword is required for each XDL
command statement.
Parameter
Each command keyword is followed by parameters used to select its processing parame-
ters. The parameters for an XDL command keyword consist of a left and right part separat-
ed by an equal sign (=).
