• Detail of the "contents of variable fields"
This field contains a string of characters in the exact order of the variable fields in the
base message. The number of characters sent must be exactly equal to the number of
spaces reserved in the base message. A bar code can be contained in a variable field.
NOTE:
In the base message, the variable fields are contained between two 12h delimiters.
E.g.:
