ArgCODE.wSingle-byte character
ReturnAlways 0
Outputs the character specified by CODE to stdout.
It checks whether the key is ^C, ^S, ^P, or ^N.

If the string exceeds the maximum number of input characters a warning is issued but it doesn't error out. Set the maximum number of input characters before calling this. If you execute it continuously with the same buffer, you can use the template function unless you clear the number of input characters obtained from the previous execution.

Usage:

pea	(FILE)
DOS	_MKDIR
addq.l	#4,sp

$FF3A<BOOKMARK:rmdir>_RMDIRDelete subdirectory
ArgFILE.lPointer to directory name
ReturnError code
Delete the subdirectory specified by FILE. The directory must be empty and you can't delete the current directory, the root directory, directories with the system or read-only attribute. When the call is successful the return value is usually 0, but when a special device driver is targeted, a positive integer may be returned.

Usage:

pea	(FILE)
DOS	_RMDIR
addq.l	#4,sp

$FF3B<BOOKMARK:chdir>_CHDIRChange current directory
ArgFILE.lPointer to directory name
ReturnError code
Change the current directory to the directory specified by FILE. When the call is successful the return value is usually 0, but when a special device driver is targeted, a positive integer may be returned. It does not work properly with Human68k version 3.02, change to a subdirectory with length of 22 characters fails.

Usage:

pea	(FILE)
DOS	_RM==CHDIR
addq.l	#4,sp

$FF3C<BOOKMARK:create>_CREATECreate file
Arg 1FILE.lPointer to file name
Arg 2ATR.wfile attribute (%XLAD_VSHR)
ReturnThe file handle of the created file. If negative, an error occured.
Create the specified file specified by FILE with the attributes specified in ATR.
If ATR is 0, it is interpreted as the Archive attribute.
If the file already exists the contents of that file will be lost. Directories, volume labels, and files with the System attribute are read-only and will not be deleted. When the MSB of ATR is set, even if the file already exists, it will not be deleted.

Usage:

move	ATR,-(sp)
pea	(FILE)
DOS	_CREATE
addq.l	#6,sp

$FF3D<BOOKMARK:open>_OPENOpen file
Arg 1FILE.lPointer to file name
Arg 2MODE.wAccess mode
ReturnThe file handle of the opened file. If negative, an error occured.
Open the file specified by FILE in the access mode specified by MODE.
If the file has the read-only attribute it will not open with write or read/write mode.

Valid values for mode:
bit 8 - Dictionary access mode
* %1 - A special file handle is used for dictionary. (Use is prohibited)
* %0 - normal

bit 6~4 - Sharing mode
* %100 always set
* %011 - Write only allowed
* %010 Read only allowed
* %001 Prohibited
* %000 Compatibility mode

bit 1 to 0 - Read/write mode
* %10 Read/write mode
* %01 Write mode
* %00 read mode

The sharing mode specified by bits 6~4 regulates sharing files between multiple processes. When multiple processes are running, each process can read and write the same file at the same time. This is potentially risky behavior and you should always specify an appropriate sharing mode to maintain exclusive control of file access.

Usage:

move	MODE,-(sp)
pea	(FILE)
DOS	_OPEN
addq.l	#6,sp

$FF3E<BOOKMARK:close>_CLOSEClose file
ArgFILENO.wFile handle

Arg 2BUFFER.lPointer to read buffer
Arg 3LEN.lNumber of bytes to read
ReturnNumber of bytes actually read. If negative, an error occured.
Read the number of bytes speficied in LEN to the buffer specified in BUFFER from the file handle FILENO. After execution the file pointer moves backward(?) by the number of bytes read. If LEN=0, read from the current file pointer to the end of the file. If the return value is less than the specified number of bytes it means that the file has been read to the end.

Usage:

move.l	LEN,-(sp)
pea	(BUFFER)
move	FILENO,-(sp)
DOS	_READ
lea	(10,sp),sp

$FF40<BOOKMARK:write>_WRITEWrite file
Arg 1FILENO.wFile handle
Arg 2BUFFER.lWrite buffer pointer
Arg 2LEN.lNumber of bytes to write
ReturnNumber of bytes actually written. If negative, an error occured.
Write the number of bytes specified in LEN to the buffer specified in BUFFER from the file handle FILENO.
After execution the file pointer moves backward(??) by the number of bytes writte. When the return value is less than the bytes specified this means the disk is full.

Usage:

move.l	LEN,-(sp)
pea	(BUFFER)
move	FILENO,-(sp)
DOS	_WRITE
lea	(10,sp),sp

$FF41<BOOKMARK:delete>_DELETEDelete file
ArgFILE.lPointer to file name
ReturnError code
Delete the file specified by FILE. You can not use wildcards, delete directories or volume labels, or files with the system or read-only attributes.

Usage:

pea	(FILE)
DOS	_DELETE
addq.l	#4,sp

$FF42<BOOKMARK:seek>_SEEKMove file pointer
Arg 1FILENO.wFile handle
Arg 2MODE.wMovement mode
ReturnOffset from the beginning of the file.
The pointer of the file specified by FILENO is moved based on the specified MODE and OFFSET. Attempts to move past the beginning or end of the file results in an error. The character device can't seek and the current position will always return 0.

MODE = 0 - Start
MODE = 1 - Current position (Negative offsets will move the pointer forward)
MODE = 2 - EOF (offset must be less than or equal to 0.)

Usage:

move	MODE,-(sp)
move.l	OFFSET,-(sp)
move	FILENO,-(sp)
DOS	_SEEK
addq.l	#8,sp

$FF47<BOOKMARK:curdir>_CURDIRGet the current directory
Arg 1DRIVE.wDrive number (0: current 1: A 2: B … 26: Z)
Arg 2BUFFER.lBuffer pointer
ReturnError code
Write the current directory of the drive specified by DRIVE into the 65 byte buffer specified by BUFFER. Does not add '\' to the root directory or '\' to the end of the string.

Usage:

pea	(BUFFER)
move	DRIVE,-(sp)
DOS	_CURDIR
addq.l	#6,sp

$FF48<BOOKMARK:malloc>_MALLOCReserve memory
ArgLEN.lNumber of bytes to reserve
ReturnPointer of allocated memory block (MSP+0x10)
d0.l = 0x81?????? the specified amount can't be reserved (0x?????? is the number of bytes that can be reserved).
d0.l = 0x8200000? Impossible to completely reserve (0x? is indeterminate).
Reserve memory with the number of bytes specified by LEN. If LEN is greater than 0x1000000 it is always an error and it is possible to check the maximum number of bytes that can be reserved.

Usage:

move.l	LEN,-(sp)
DOS	_MALLOC
addq.l	#4,sp

$FF49<BOOKMARK:mfree>_MFREERelease reserved memory
ArgMEMPTR.lPointer to memory block
ReturnError code
Releases the memory block specified by MEMPTR. When MEMPTR=0, release all memory reserved by you.

Usage:

pea	(MEMPTR)
DOS	_MFREE
addq.l	#4,sp

$FF4A<BOOKMARK:setblock>_SETBLOCKResize memory block
Arg 1MEMPTR.lPointer to memory block
Arg 2LEN.lNumber of bytes to reserve
ReturnError code
d0.l=0x81?????? Unmodifiable (0x?????? is the number of changeable bytes)
d0.l=0x8200000? Completely unmodifyable (0x? is indeterminate)
Change the memory block specified by MEMPTR to the size specified by LEN. If LEN is greater than 0x1000000 it is always an error and it is possible to check the maximum number of bytes that can be changed.

Usage:

move.l	LEN,-(sp)
pea	(MEMPTR)
DOS	_SETBLOCK
addq.l	#8,sp

$FF4C<BOOKMARK:exit2>_EXIT2Exit with return code

Arg 1FILE.lPointer to file name
Arg 2ATR.wFile attribute (%XLAD_VSHR)
ReturnThe file handle of the created file. If negative, an error occured.
Create a temporary file specified by FILE with attributes ATR. The file name can contain '?', it is replaced by a number when created. It increments until it becomes a file name that does not exist then creates it. Note that the file name specified by FILE can be rewritten by this DOS call.

Usage:
