TOPIC:

Does the CT 8.9 and it's FPC support anonymous procedures and functions?

The code CLASSES.PAS contains the type TThreadProcedure = reference to procedure, but attempting to declare a variable of type "reference to procedure" generates an error. Also, code containing anonymous procedures fails to compile, even though, according to the FPC version, it should support this.

What's the verdict?

Yes Sir
CT 9.0 support anonymous procedures and functions.
with

{$MODE DELPHI}
{$MODESWITCH ANONYMOUSFUNCTIONS}

you can use and :
{$MODESWITCH FUNCTIONREFERENCES}
{$MODESWITCH UNICODESTRINGS}   
{$ModeSwitch ADVANCEDRECORDS}  
{$ModeSwitch TYPEHELPERS}
{$ModeSwitch NESTEDPROCVARS}

For sample look at 
typhon\components\packages_pl\pl_Skia\source\libskiaobj.pas ### at line: 271
typhon\components\packages_pl\pl_Tensorium\source\ntensors.pas ### at line: 212

 

Thank you very much, sir!
It works in version 8.9 too:

{$mode ObjFPC}{$H+}
{$MODESWITCH ANONYMOUSFUNCTIONS}
{$MODESWITCH FUNCTIONREFERENCES}
