Attribute values

Conventions have been established for attribute values.

The following conventions have been established for attribute values:

• Printer names are of the form 4201-3, reflecting the printer name (4201) and model number (3).
• File names in the Predefined Database are of the form PrinterType.DataStreamType; for example, 4216-31.asc indicates a 4216 Model 31 printer and an ASCII data stream.
• File names in the Customized Database are of the form QueueName:QueueDeviceName, such as proq:mypro.
• Attribute values can contain a \ (backslash) followed by one to three octal digits to represent non-ASCII values. A \ (backslash) that does not begin an octal sequence should be represented by either \\ or \134.
• Characters can be represented by hexadecimal notation of the form \xXX, where XX represents a hexadecimal value.
• Boolean values can be represented by a + (plus sign) for true, and an ! (exclamation point) for false.
• Because attribute values reside in colon files, a colon character must not appear in the attribute value. Instead, a colon should be represented by \072.
• An attribute value that references an integer attribute requiring translation from a lookup table should always appear in a colon file after the referenced integer attribute: For example, from the string red to an equivalent integer value of 2. Integer values are created from a colon file in the same order they are defined in the colon file. Listing the attribute value first ensures that when the integer attribute is referenced, it has been converted before it is referenced by the %G escape sequence.
• Run all the shell commands using ksh instead of bsh.
