LIB_PATH, READ_PATH, WRITE_PATH - file search pathes

Calling sequence:
LIB_PATH := string ...
READ_PATH := string ...
WRITE_PATH := string

Parameter:

string   --  character string

Summary:

LIB_PATH determines the directories where library files are searched for by the
functions loadproc and loadlib . By default, in the UNIX version of MuPAD
LIB_PATH is defined as the subdirectory $MuPAD_ROOT_PATH/share/lib, but
can be re-defined using the option -l.

READ_PATH determines the search path for the function read.  read firstly
searches for a file in the directories given by READ_PATH, then in the current
directory and finally in the directories given by LIB_PATH.

More than one directory can be given by the variables LIB_PATH and READ_PATH
being assigned a sequence of character strings.

WRITE_PATH determines the directory, into which the functions fopen , fprint ,
write and protocol write files. If WRITE_PATH is not defined then the files

are written into the current directory.

Important: The directories given by LIB_PATH, READ_PATH or WRITE_PATH,

when concatenated with a file name, must be valid path names!
Path names are system dependent.  Under UNIX a subdirectory is started
with a /; on the Macintosh a : is used instead. Use the function pathname
to specify system independent pathnames.
