Is there a way to do this programmatically without running "ver"?
0.73 fixed a bug regarding the child program initial stack value (though the initial stack value is wrong - 0xffff instead of 0), which breaks some of my game fixes for 0.72. In case people some people upgrade and some don't, it would be nice to detect the version and behave properly in both cases.

The VESA BIOS has (bad luck if you run in vgaonly or CGA mode)

0.73 has a string at 0xfe061 that 0.72 doesn't have

1+1=10
