DCL:GRPH1:SWPACK: Machine-Dependent Routines
In GRPH1, a number of databases is necessary to draw graphics. (All original 
data is described in ASCII format.) In the standard library, these original 
database files are stored under src/env1, and they are converted as necessary 
and copied into the directory indicated by the internal variable 'DSPATH'.
Of the below database files, the "font file" and the 
"color/tone index conversion table file" must always be present.
For details such as file descriptions, see the memos in each directory   
under  env1.  
Besides the database files below, the map information data used by GRPH2 are also filed under env1.
