Signature can be said to be do wat the level identifier of
physical file do. It help the programs to know if any
service program is updated or not . As many program would
be using this service Program so compliting all of them is
cumbersome so Binder langanguage provide the solution .
When the program calling the service program is compiled
its stores the signature of the service program . If the
service progranm is changed so does the signature of it.
The work around is the Binder language For eg

STRPGMEXP PGMLVL(*CURRENT)
EXPORT SYMBOL(A)
EXPORT SYMBOL(B)
EXPORT SYMBOL(C)
ENDPGMEXP

if changes r made to Service program(new procedure D is
added0 the Binder language will be :

STRPGMEXP PGMLVL(*CURRENT)
EXPORT SYMBOL(A)
EXPORT SYMBOL(B)
EXPORT SYMBOL(C)
EXPORT SYMBOL(D)
ENDPGMEXP
STRPGMEXP PGMLVL(*PRV)
EXPORT SYMBOL(A)
EXPORT SYMBOL(B)
EXPORT SYMBOL(C)
ENDPGMEXP


now one need not to compile the programs calling service
program & the program will run proeperly as thr will be no
signature violation as the binder language have both
current and previous signature.
