SYNOPSYS

       #include "mut.h"
       void mbkenv();

DESCRIPTION

       The mbkenv function set the user preferences through unix environment variables. if all the variables are
       not defined, default values are used.

       MBK_WORK_LIB                  internally  char  ∗WORK_LIB,  sets  the  working  directory for reading and
                                     writting, result of a savephfig for example. Its value is "." by default.

       MBK_CATA_LIB                  internally char ∗∗CATA_LIB, sets the working directories for reading  only.
                                     This  is  a  set  of  pathes,  like  the unix PATH variable.  It is used in
                                     loadlofig for example. Its value is "." by default.

       MBK_CATAL_NAME                internally char ∗CATAL_NAME, sets the name of the catalog file,  needed  to
                                     know where to stop a flatten, and so on. Set to "CATAL" by default.

       MBK_SEPAR                     internally  char  SEPAR,  sets the character used for string concatenation.
                                     Used for example in concatname.  By default it is ".".

       MBK_VDD                       internally char *VDD, sets the name to be used as power  level  recognition
                                     pattern  by  the tools based upon mbk that needs to identify supplies.  The
                                     default is "vdd".

       MBK_VSS                       internally char *VSS, sets the name to be used as ground level  recognition
                                     pattern  by  the tools based upon mbk that needs to identify supplies.  The
                                     default is "vss".

       MBK_TRACE_MODE                internally char TRACE_MODE, output information in each mbk access  function
                                     it enters.  Used for debugging purposes.  By default it is 'N'.

       MBK_DEBUG_MODE                internally  char  DEBUG_MODE,  output  information in function that makes a
                                     check on its values : mostly parsers for debug. It  is  very  verbose,  and
                                     mostly unusable. No mbk function take care of it.  By default it is 'N'.

       MBK_FAST_MODE                 internally  char  FAST_MODE.  If  set  to  'Y',  no consistency checked are
                                     performed on many mbk functions. This can work only on a  program  that  is
                                     warrantied  to  be bugless, else undefined results would occur.  By default
                                     it is 'N'.

       MBK_IN_LO                     internally char IN_LO[5]. Defines the logical input format demanded by  the
                                     user.  See  MBK_IN_LO(1) for a list of valid formats.  By default its value
                                     is "al".

       MBK_OUT_LO                    internally char OUT_LO[5]. Defines the logical input format demanded by the
                                     user. See MBK_OUT_LO(1) for a list of valid formats.  By default its  value
                                     is "al".

       MBK_IN_PH                     internally  char IN_PH[5]. Defines the logical input format demanded by the
                                     user. See MBK_IN_PH(1) for a list of valid formats.  By default  its  value
                                     is "ap".

       MBK_OUT_PH                    internally char OUT_PH[5]. Defines the logical input format demanded by the
                                     user.  See MBK_OUT_PH(1) for a list of valid formats.  By default its value
                                     is "ap".

       MBK_SCALE_X                   internally long SCALE_X. Defines a scale factor  for  all  coordinates,  in
                                     order  to  be  able  to  use  files  that  works with half lambda rules for
                                     example.  Parsers, drivers and genlib's  macros  use  it  extensivly.   Its
                                     value is ten by default.

       MBK_IN_FILTER                 internaly  IN_FILTER.  Filter string for reading compressed Alliance files.
                                     It has no value by default, means no filter is used.

       MBK_OUT_FILTER                internaly OUT_FILTER. Filter string for writing compressed Alliance  files.
                                     It has no value by default, means no filter is used.

       MBK_FILTER_SFX                internaly  FILTER_SFX.  Extention  of compressed files.  It has no value by
                                     default, means no filter is used.
