|Arg 1|DRIVE.w|Drive number (0: current 1: A 2: B ... 26: Z)|
|Arg 2|BUFFER.l|Buffer pointer|
|Return|Error 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.|||

^$FF48^<BOOKMARK:malloc>_MALLOC^Reserve memory^
|Arg|LEN.l|Number of bytes to reserve|
|Return|Pointer 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>_MFREE^Release reserved memory^
|Arg|MEMPTR.l|Pointer to memory block|
|Return|Error code||
|Releases the memory block specified by MEMPTR. When MEMPTR=0, release all memory reserved by you.|||

Usage:

^$FF4A^<BOOKMARK:setblock>_SETBLOCK^Resize memory block^
|Arg 1|MEMPTR.l|Pointer to memory block|
|Arg 2|LEN.l|Number of bytes to reserve|
|Return|Error code \\ d0.l=0x81?????? Unmodifiable (0x?????? is the number of changeable bytes) \\ d0.l=0x8200000? Completely unmodifyable (0x? is indeterminate)||

Usage:

	move.l	LEN,-(sp)

|Arg|None||
|Return|Exit code||
|Examine the exit code of the executed process. It is the same as the return value of //DOS _EXEC(MODE=0,4)//|||

|Arg 2|ATR.w|File attribute (%XLAD_VSHR)|
|Return|The 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:
	move	ATR,-(sp)
	pea	(FILE)
	DOS	_MAKETMP
	addq.l	#6,sp

|Arg 1|FILE.l|Pointer to file name|
|Arg 2|ATR.w|File attribute (%XLAD_VSHR)|
|Return|The file handle of the created file. If negative, an error occured.||
