But the instance will only be created if you call a constructor using the type.

Yeah you certainly need to assigned it to the variable or obviously that variable will be uninitialized and thus “d.add” will be an error.

Re: [fpc-pascal] Question on TFPGMap
Sorry copy and paste error. d = decode. Corrected below. But I think I
see what you mean. Just assigning a type to decode doesn't initialize
it. But the compiler is happy with it, i.e. it doesn't call as illegal
the statement "decode.create".

This doesn’t make sense. It should be
d := specialize TFPGMap.Create;
Right? What is “decode” and why aren’t you assigning it to anything?

[fpc-pascal] Question on TFPGMap
I have a simple example that gives an access violation on the latest
macos (fpc mode, i.e. no mode switch). What am I missing? Thanks in advance:
program ex;
uses fgl;
var d: specialize TFPGMap;
begin
decode.create;
decode.add('X', 1);
end.
An unhandled exception occurred at $0001023917DE:
EAccessViolation: Access violation
$0001023917DE

Pete
