Note that there is a gap in edit numbers from 838 through 849 to allow for future patches to the 4.8 releases.

MSGBOX.SBX 1.0(101) now supports a HELP button in message boxes. To add a HELP button, add 16384 to the BTNFLAG argument to MSGBOX.SBX. The subroutine returns 9 if the button is clicked.

COMPIL now invokes /A automatically (as needed) even if OPTIONS=STRICT. It invokes /AV automatically only if STRICT not set.
