Brief
Set current directory
Input
- DS:DX → ASCIZ pathname to become current directory (max 64 bytes)
Return
- CF clear if successful
- AX destroyed
- CF set on error
- AX = error code (03h) (path not found)
Notes
if new directory name includes a drive letter, the default drive is not changed, only the current directory on that drive
changing the current directory also changes the directory in which FCB file calls operate
