MISCELLANEOUS
@GetDate (2Ah) and @SetDate (2Bh)
Gets or sets the system date
Syntax: @GetDate
@SetDate month, day, year
Arguments: year = 16-bit year (1980-2099)
month = 8-bit month (1-12)
day = 8-bit day (1-31)
Return: For @GetDate:
AL = Day of week (0 = Sunday, 1 = Monday, etc.)
CX = Year (1980-2099)
DL = Month (1-12)
DH = Day (1-31)
For @SetDate:
AL = If date was valid 0, else -1
Registers used: AX, CX, and DX
@GetTime (2Ch) and @SetTime (2Dh)
Gets or sets the system time
Syntax: @GetTime
@SetTime hour,minute,second,hundredth
Arguments: hour = 8-bit hour (0-23)
minute = 8-bit hour (0-59)
second = 8-bit hour (0-59)
hundredth = 8-bit hour (0-99)
Return: For @GetTime:
CL = Hour (0-23)
CH = Minute (0-59)
DL = Second (0-59)
DH = Hundredth (0-99)
For @SetTime:
AL = If time was valid 0, else -1
Registers used: AX, CX, and DX
@GetVer (30h)
Gets the DOS version
Syntax: @GetVer
Argument: None
Return: AL = Major version (0 for versions prior to
2.0)
AH = Minor version
BH = OEM serial number
BL:CX = 24-bit user number
Register used: AX, BX, and CX
@GetInt (35h) and @SetInt (25h)
Gets or sets the vector for a specified interrupt routine
Syntax: @GetInt #interrupt
@SetInt #interrupt, &vector [,segment]
Arguments: interrupt = 8-bit interrupt number
vector = Offset of interrupt routine
segment = Segment of routine - if none given, DS
assumed for data; segment ignored for
code labels
Return: @GetInt = None
@SetInt = ES:BX points to interrupt routine
Registers used: AX for both; ES and BX for @GetInt; DS and
DS for @SetInt
