GN_Pdt, convert an internal date to an ASCII string
RST 20H, DEFW $0809
IN:
HL = 0,1,2 not allowed HL > 255, HL points to 3 byte internal date (low byte first) DE = 0, result to stream IX DE = 1, result to filter IX DE = 2, not allowed DE > 255, result written at (DE) A0 = 1, enable zero blanking A1 = 1, output leading space A2 = 1, output trailing space A3 = 1, force American format (day, month, date, year) A4 = 1, force European format (day, date, month year) A5 = 1, force C as inter-field delimiter A6 = 1, date suffix output A7 = 1, century output B0 = 1, output text month, reset for numeric month B1 = 1, output expanded day, reset for compressed day B2 = 1, output expanded month, reset for numeric month B3 = 1, output day, reset for no day B4 - B7, undefined C = optional inter-field delimiter (A5 = 1) IX = optional output handle (if DE = 0,1)OUT, if call successful:
Fc = 0 DE = points to next character after result (if DE(in) > 255), else contains number of characters written to destination.OUT, if call failed:
Fc = 1 A = error code: RC_BAD ($04), bad parameters RC_ROOM ($07), no room to perform conversionRegisters changed after return:
..BC..HL/IXIY same AF..DE../.... differentNotes:
A3 = A4 = 0 will output in system defined format. A3 = A4 = 1 undefined result. A5 = 0 will use space as inter-field delimiter.Bugs:
Will fail if source or destination addresses are in segment 2.Related calls:
