How do Informix version numbers work?

The 1.23 is a pretty orthodox major/minor/maintenance release number except that there is no dot between the 2 and the 3. The U indicates (32-bit) Unix; alternative characters can appear in that position, including H (32-bit code for a 64-bit HP-UX platform), F (64-bit Unix), T (WinNT et al), P (Perl) and a host of others. The C is another level of maintenance release; the letters start at C and move through the alphabet. The 4 is another sublevel of maintenance release. Occasionally, you’ll find more characters after the UC4 (eg UC4X2 – a second patch port of the UC4 release, or UC1A1 for an alpha-1 pre-release). And there are some other version number schemes (N123 for a nightly build instead of UC4).
