Invalid Commands
Invalid commands are in two general types: those with syntax errors and those with syn-
tax or semantic warnings. The printing system handles each of those types different
ways.
Syntax errors contain errors such as unrecognized commands and command modifiers,
strings with missing closing double quotations, numeric values with missing digits
before the decimal points, and numeric values encountered when alphanumeric values
are to be expected. The printing system ignores the entire PJL commands when it
receives commands having syntax errors. Some examples follow.
The JOB command’s NAME option requires double quotations around its value part.
Valid command:
@PJL JOB NAME = "Job Number 50" <LF>
Invalid command:
@PJL JOB NAME = "Job Number 51 <LF>
The closing quotation is required.
Syntax warnings and semantic warnings are issued for such commands that have unsup-
ported options, values out of range, values missing or of the incorrect type, or values
added when none are allowed. When the printing system receives commands with syntax
or semantic warnings, the part of the command including the warning is ignored.
In the following example, the START option is valid for the JOB command.
Valid command:
@PJL JOB START = 1 <LF>
While in the following, FINISH is not a valid option and ignored (END should be used).
Invalid command:
@PJL JOB START = 1 FINISH = HOME <LF>
