Xerox Print Description Language (XDL)
The ASCII string type allows hexadecimal representation of characters to be embedded in
a string. This is done by preceding the hexadecimal representation of the character with an
! character. For example:
IDEN PREFIX=A'ABC!44EF'
is equivalent to
IDEN PREFIX=X'414243444546'
The three-character sequence required for a hexadecimal representation of a character re-
sults in one byte.
Two successive ! characters (!!) are necessary to represent one actual ! character when
printing. The two-character sequence (!!) results in one byte.
EBCDIC
EBCDIC constants are used for value and string constants. They must be preceded by the
characters E apostrophe (E') and followed by an apostrophe character ('). The EBCDIC
string type allows hexadecimal representation of characters to be embedded in a character
string. This is done by preceding the hexadecimal representation of the character with an !
character.
For example:
IDEN PREFIX=E'ABC!C4EFG'
is equivalent to the hexadecimal
IDEN PREFIX=X'C1C2C3C4C5C6C7'
Each character represented in EBCDIC results in one byte. Each two-character sequence
representing a character hexadecimally results in one byte.
Note that EBCDIC is the default, therefore the E 'xxx' is usually not required.
Ink references
Ink references may occur as one of the following:
•
ink index (numerical
•
'ink name' (always enclosed into apostrophes)
Ink names may be written in one of the following formats:
