Reading this pseudo variable will give the assembler version according to
the following formula:
VER_MAJOR*$100 + VER_MINOR*$10
<tt>(VER_MAJOR * 0x100) + VER_MINOR</tt>
It may be used to encode the assembler version or check the assembler for
special features not available with older versions.
The upper 8 bits are the major-, the lower 8 bits are the minor version.
Example:
Version 2.14 of the assembler will return $2E0 as numerical constant when
reading the pseudo variable <tt/.VERSION/.
For example, version 47.11 of the assembler would have this macro defined as
<tt/0x2f0b/.
Note: until 2.19 this pseudo variable was defined as <tt>(VER_MAJOR * 0x100) + VER_MINOR * 0x10</tt> -
which resulted in broken values starting at version 2.16 of the assembler. For
this reason the value of this pseudo variable is considered purely informal - you should
not use it to check for a specific assembler version and use different code
according to the detected version - please update your code to work with the
recent version of the assembler instead (There is very little reason to not use
the most recent version - and even less to support older versions in your code).
