setpacking
Syntax | bool setpacking – |
Definition This operator determines the type of executable arrays subsequently created by the PostScript interpreter’s scanner. It sets the array packing mode to the specified boolean value. The value true selects packed arrays. The value false selects ordinary arrays.
The packing mode affects only the creation of procedures by the scanner when it encounters program text bracketed by { }, during interpretation of an executable file or string object; or during execution of the token operator.
It does not affect the creation of literal arrays by the [ ] operators, or by the array operator.
The array packing mode persists until it is overridden by another execution of setpacking or is undone by restore.
Example:
systemdict/setpacking known {/savepacking currentpacking def true setpacking
} if
... arbitrary procedure definitions ...
systemdict/setpacking known [savepacking setpacking] if
