Notes
ASCII string have to use the local date string (dates are fully country localized since OZ 4.5).
Setting A3=0 and A4=0 will mean that the PANEL settings for the date format will be used. A3=A4=1 will use European format. The routine will return a syntax error (RC_SNTX) if A5=1 and the character passed in C(in) is not the terminator of the string to be converted. Please note that returned internal format is in high byte low byte register sequense (A = high byte, C = low byte).
Source in HL can not be in segment 1 used by Date Filter Table. Destination in (DE>255) can be inside segment 1.
