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.

EXAMPLE

       #include "mut.h"
       #include "mlo.h"
       lofig_list ∗load_fig(name)
       char ∗name;
       {
          mbkenv(); /∗ make sure the good environnement is used ∗/
          return getlofig(name, 'A');
       }
