Hi folks,

I want to define a structured variable as global variable. So I think
about using the COMMON block to share this variable with others
procedures. However, IDL does not enable to use this variable in a
procedure without declaration.

pro A
COMMON SHARE1, X ;how to define x as a structure ?
X.a = 1
X.b = 2
end

pro B
COMMON SHARE1
X.a = 4 ; this is not permitted
X.b = 5
end

Does anyone know how to resolve this problem ?
Thanks for your help.
Best regards,
Tri.

PS. Thanks also all of you for all your precedent responses.
