Note
If you inadvertently enter a number in the T parameter which does not appear
in the preceding table, the printer regards the complete sequence as a font
call and not as a barcode call, so any unwanted fonts are activated and the
printer attempts to print your base data instead of outputting the barcode.
Warning
If invalid values – i.e. values which differ from the validity ranges mentioned
above – are entered for any of the parameters, PCL Barcode Flash prints out
an error message instead of the barcode symbol. The same happens when
the desired base data cannot be reproduced by means of the selected
barcode type.
3.2.7 Alternative Escape characters
There are applications, primarily in the mainframe sphere, from which characters
below ASCII 32 (= 20hex) cannot be output, or output only with difficulty. In such
cases, you have the option of replacing the <Esc> character (ASCII character 27)
with any other character of the list below.
Using the PRESCRIBE sequence
!R!VBST;F;EXIT;
you can activate a mode in PCL Barcode Flash which uses the character ~ (ASCII
126) as an alternative character for <Esc>. If you have activated this mode, you can
use ~ instead of <Esc> for the Escape sequences, and PCL Barcode Flash will
understand ~ as <Esc> as well. In spite of this, <Esc> can still be sent as <Esc>
and ~ behave exactly the same in this mode.
However, you can also replace the alternative Escape character with another
character by means of the following Escape sequence:
<Esc>**36J or <Esc>**$J
or
~**36J or ~**$J
This sequence causes the $ character (ASCII 36), for example, to be used from this
point on instead of ~ as the alternative Escape character.
The following can also be used as alternative Escape characters:
