FT_CHDIR()
 Change the current directory
──────────────────────────────────────────────────────────────────────────────

 Syntax

     FT_CHDIR( <cDirName> ) -> nResult

 Arguments

    <cDirName> is the name of the desired directory.

 Returns

    0  if successful
    3  if path not found
    99 if invalid parameters passed

 Description

    Use this function if you prefer to change the active directory
    instead of relying on the SET PATH command.

    The source code is written to adhere to Turbo Assembler's IDEAL mode.
    To use another assembler, you will need to rearrange the PROC and
    SEGMENT directives, and also the ENDP and ENDS directives (a very
    minor task).

 Examples

    FT_CHDIR( "C:\CLIPPER" )
    FT_CHDIR( "\" )
    FT_CHDIR( "..\SOURCE" )
