OS/2 v2.1+ Virtual DOS Machine - GET LOADING MESSAGE

AH = 64h
DX = 0008h (function number)
CX = 636Ch (magic value, "cl")
BX = 0000h (indicates special request)

Return:
DS:DX -> '$'-terminated message "Loading. Please wait."

Notes: If CX is not 636Ch on entry, INT 21/AH=6Ch is invoked, because a bug in OS/2 1.x FAPI erroneously called AH=64h instead of AH=6Ch. This function permits National Language Support for the initial message displayed while WinOS2 starts a full-screen session
