Set current directory

• DS:DX → ASCIZ pathname to become current directory (max 64 bytes)

• CF clear if successful
  • AX destroyed
• CF set on error
  • AX = error code (03h) (path not found)

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
