Dear David,
I made a simple example which shows the problem:
--------------------------------
;file test1.pro
FUNCTION test1
return,-1
END
--------------------------------
;file test2.pro
PRO test2
test1=[5,4,6]
print,test1(0:1)
END
---------------------------------
After strting idl:
;this fails
print,test1()
test2
;output:
IDL> print,test1()
% Compiled module: TEST1.
-1
IDL> test2
print,test1(0:1)
^
% Syntax error.
At: /users/pgrigis/test2.pro, Line 5
% Compiled module: TEST2.
% Attempt to call undefined procedure/function: 'TEST2'.
% Execution halted at: $MAIN$
compare with:
;this works
test2
print,test1()
test2
;output
IDL> test2
% Compiled module: TEST2.
5 4
IDL> print,test1()
% Compiled module: TEST1.
-1
IDL> test2
5 4
Quite bad, isn't it?
Cheers,
Paolo
