The FARMANAGERVERSION constant defines the current FAR Manager version and has the following format - 0xBBBBXXYY:

BBBB = build number (343 = 0x0157)
XX = major version (FAR 1.70 = 0x01)
YY = minor version (FAR 1.70 = 0x46)

So for FAR Manager 1.70 beta 3 build 343 this constant will be: 0x01570146

The FARMANAGERVERSION constant is formed using the MAKEFARVERSION macro.
