Using uninitialised variables is virtually always bad, regardless of the scope. And the fact that global variables are zeroed at the program start is afaik not defined by the Pascal standard. It's just a side effect of the way most operating systems work.
I think I didn't get your point. What about this piece of code: interface function foo: tfoo; implementation var _foo: tfoo; function foo: tfoo; begin if not assigned(_foo) then _foo := tfoo.create; result := _foo; end; Is it safe? -- Joao Morais _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
