NOTE: Commas and blanks cannot be used
interchangeably. Many commands require commas to
separate the parameters, and blanks are not valid delimiters.
The syntax diagram in each command and parameter
description shows which delimiters to use.
• Uppercase text: Use UPPERCASE letters when coding PDL
commands. Comments, however, need not be in uppercase.
The following LINE command example contains three
parameters. The right part of the VFU parameter is a reference
to an identifier "VFU1." The right part of the DATA parameter has
two components that are value constants, and OVERPRINT
uses keyword constants.
Table 1-3.
LINE VFU=VFU1, DATA=(1,10),
OVERPRINT=(PRINT,DISP);

Command syntax conventions

The command descriptions use the syntax conventions shown in
the table below.
