SUBROUTINE GG_INIT ( mode, iret )

C************************************************************************

|
C* GG_INIT *
|
|
C* *
|
|
C* This subroutine initializes the GEMPLT plotting package. The *
|
|
C* current map file is set to the global map file name found in *
|
|
C* $MAPFIL. Thus, it is necessary to call IP_INIT before calling this *
|
|
C* subroutine. If IP_INIT has not been called, the map file will not *
|
|
C* be defined. *
|
|
C* *
|
|
C* In the past, this subroutine set default margins for map and graph *
|
|
C* mode. Currently, margins will not be set or changed in GG_INIT. *
|
|
C* Margins can be specified by the user in the input for PROJ. The *
|
|
C* margin definition will be extracted by GG_PROJ and set in GG_MAPS. *
