This means that the type
of data is unknown. This can appear for entire records when nothing about
the record is known, or for isolated areas of records where there are knowlege
gaps.
The editor used is a Hex editor, since the length of the data items
is unknown.
This denotes a record for which
has multiple data members and at least some of the members are known. Clicking
on this will expand the tree to show the data members in the record.
This means a Boolean one or
zero. I have found that BOOL types in AIR files are all 4 bytes, just as
the ones in M$ C compilers. All of those extra bits are unused.
An 8-bit signed integer. This
is the same as a C language "char". It can range from -128 to 128. There
are no decimal capabilities to integer types.
A 16-bit signed integer. Ranges
from -32768 up to 32768.
A 32-bit signed integer. Ranges
from -2147483648 all the way up to 2147483647.
A 32-bit signed value that
can contain a decimal place. this is the only data member in an AIR file
that has a decimal place, and it is rarely used.
The record contains text only.
Note that the text entered here has no effect on the flight or visual models.
It is for information only.
I plan on adding the unsigned data types in the future, if indeed there actually are any used in an AIR file!
