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
