/******************* IMPORTANT ********************
|
|
Due to a limitation of the DecStation loader any function (including
|
|
library functions) which is linked to yap can not be called directly
|
|
from C code loaded dynamically.
|
|
To go around this problem we adopted the solution of calling such
|
|
functions indirectly
