[mkgmap-dev] [mkgmap-svn] Commit r597: fix stupic typo: use given recsize instead of constant 5

Tue Jan 25 09:17:48 GMT 2022

Hi Gerd

Going through the Mdr7 p and s values and mdr32/3 table (looks good
now) I can't see any logic to it.

Mdr32/33 has 210 records, which, as you say, look like common parts of
street names.

Mdr7 p= has values  0..2271. most are 0, low values are common, higher
values mostly unique in ascending alphabetic sequence of MDR7 record#

s= has values 0..22 and values > 0 seem to occur when there is a shield
in the LBL

The values of 2272 / 23 don't correspond to the number-of-records in
any MDR section

nameOffset seems reasonable, commonly pointing to the first digit in
the street name.

Mdr30/31 has 1 record: "HWY"

I think I have to give up looking for the meaning of mdr30..33 and the
p/s values
