Chapter 7: Programming Guide 7-135
Ten parameters are more than enough to specify all variable length
fields with a field separator each and other status information that may
be helpful to an application. More than 10 parameters are not
recommended because they use up space in non-volatile memory
(NVRAM) available for the exception table.
The parsing parameter string is stored packed in NVRAM starting at
word 10, with the total byte length stored in the high order byte of
word 10. While most parameters take two bytes of NVRAM, the
following parameters take only one byte: B, D, E, S, L. None of the
parsing examples in the following section take more than 14 bytes
(seven words) of NVRAM.
The exception table starts at word 20. If the parsing parameter string
extends into word 20, then the first exception table entry is unavailable.
