PDL principles and procedures

Using LCDS Print Description Language

Command syntax

For the system to read and process any command you put in
your JSL, you must place all elements in the proper order and
use the correct symbol or amount of space to separate them.

Syntax rules

When you enter your PDL commands at the print server,
workstation, or host keyboard, you must follow these syntax
rules in order for the system to recognize the commands.

Abbreviations: Command and parameter keywords can be
shortened to the first three letters; for example, POSITION
may be entered as POS, OUTPUT as OUT, etc.
NOTE: The only exception to this abbreviation rule is the
parameter FOR, which the system could interpret as
FORMAT, or FORM, or FORMS. Therefore, be sure to use
the full spelling to represent FORMAT or FORM(S).

Blank spaces: You may use blanks anywhere in the JSL
except in keywords and constants.

Continuation lines: The FreeFlow Print Server LCDS
systems accept continuation lines in DJDEs. The following is
an example of a DJDE using a continuation line.
NOTE: Use of continuation lines is not recommended
because the results are unpredictable

Incorrect structure for FreeFlow Print Server LCDS
systems:

DJDE FONTS=(fn1,fn2,fn3,...,fn13,
DJDE fn14,fn15,fn16);

Valid structure for FreeFlow Print Server LCDS systems:

End of a command: Place a semicolon (;) at the end of
every PDL command.

End of a JSL: Use the END; command to signal the end of a
JSL or other file such as a PDE, CME, or STOCKSET.

End of all JSLs: To signal the end of all JSLs, PDEs, CMEs,
TSTs, or STOCKSETS that are being processed, enter END
followed by a semicolon (;) twice, as shown below.

DJDE FONTS=(fn1,fn2,fn3,...,fn13),;

DJDE FONTS=(fn14,fn15,fn16),;
