Problem

Solutions: WordPerfect Printer Definition Language (WPDL) is discussed in the appendix section of the PTR manual (pages 295-320). WPDL variables are always displayed in uppercase letters. Decimal character strings are enclosed in brackets and sent directly to the printer, whereas decimal numbers without brackets are used by WP to calculate values (pg. 12).

WP needs only a Yes or No answer in the expressions column for some information. If you enter a command that is invalid, WP will display an "Error: Invalid Command" prompt. This generally means a missing parenthesis, quotation mark, etc. (pg. 13).

Built-in variables are generally displayed in uppercase letters in an expression. User-defined variables are usually displayed in lowercase letters. However, they can both be typed in either uppercase or lowercase (pg. 297.)

There are two types of WPDL phrases; Character Strings and Numeric Strings. A Character String is always sent to the printer. They can be entered by their decimal, Hex, Octal, Binary, Character or ASCII values. Numeric Strings are either sent to the printer or calculated and the result is sent to WordPerfect. In some circumstances, they can be combined into one command.

If there is more than one numeric string in an expression, only the calculated value of the last string is sent to WP. A space, tab or blank lines must be used to separate one string from another in Character strings.
