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.

       lofig_list ∗load_fig(name)
       char ∗name;
       {
          mbkenv(); /∗ make sure the good environnement is used ∗/
          return getlofig(name, 'A');
       }
