I am porting a large amount of existing Pascal code (MetaWare) to Free
Pascal. Unfortunately, this code makes extensive use of nested
procedures, and the nested procedures often reference variables in the
enclosing scope.
I know that I can't pass the nested routine by address to another
procedure; I get errors like the following:
intjob4_intday.pas(400,47) Error: Incompatible type for arg no. 3: Got
"<address of local procedure(StdStr04);Register>", expected "<procedure
variable type of procedure(StdStr04);Register>"
Can I get around this restriction by inlining the procedure which is
being passed the nested procedure as an argument?
For example, let's say the A is the enclosing procedure, B is the nested
procedure, and B is being passed as a parameter to C.
Procedure A;
Procedure B;
Begin
C(@B);
End;
Can I inline procedure C? Will this work? (My initial test with fpc
2.4.0 suggests it doesn't work).
