Time for a progress report.
Small steps forward and I have now generated a map that begins to look promising.
The generated map works fine in my gpsmap64s also.

The problem with editing the huge (>300 000 records) dbf files I had using DBF Commander almost stopped me when 24 h of cpu was not enough but I found another program. The DBF Viewer 2000 did the same job in two seconds, what a relief! (30 days trial license and not too expensive so I can consider buying it).

I have added 9 layers so far and all works more or less as expected but I need to learn more on some parameters.
The generated typ file works fine and can be edited with TYPViewer.
The "Detail Count" must be controlled better, now all details show up disregarding scale. I mostly use the type "CUSTOMIZABLE_LINE_XX)" and the count is 3 as default.
"Number of feature layers" is 3 by default, what does this really mean, can be increased to 5? And the handling of "Scale of layers" must be understood better (by me...)
When editing the look of bitmaps and lines there is a choice of "Wide Tool" or "Thin Tool", I have not figured out the effect of that yet.
And I hope to get the background colour to white (255,255,255) which is not the case in the FriPro v4 which have a grey shadow also over areas defined as white in the typ file.

Your info works and I can alter the licence file to suit my preferences.

I will continue with adding more layers like colours for fields, woods, parks etc. and houses and so on.
