%%3800_POSTNET
This system variable returns the 38 characters to be used with a particular POSTNET™ font to print a delivery point barcode (DPBC) on an IBM Model 3800 printer.
For compatibility with 3800 printers, EngageOne™ Enrichment adds two alphabetic characters to each number to be an EBCDIC representation of the POSTNET™ barcode, as follows:
| To the number | EngageOne™ Enrichment adds | 
|---|---|
| 1 | BC | 
| 2 | DE | 
| 3 | FG | 
| 4 | HI | 
| 5 | JK | 
| 6 | LM | 
| 7 | NO | 
| 8 | PQ | 
| 9 | RS | 
| 0 | TU | 
In addition, EngageOne™ Enrichment uses A as the leading framing character for the POSTNET™ barcode and Z as the trailing framing character. For example, the %%3800_POSTNET value for 40503-2793-02 is:
A4HI0TU5JK0TU3FG2DE7NO9RS3FG0TU2DEXXXZ
where XXX is the one-digit checksum and its accompanying alphabetic characters. This allows users to use a 3800 font to translate the 38 characters into the actual POSTNET™ barcode.
