function-pointer

Hello,

From ISO spec:

production:

expression can be variable-access

variable-access can be function-identified-variable

function-identified-variable is pointer-function '^'

pointer-function is function-access

function-access can be entire-function-access

entire-function-access is function-designator

function-designator is function-name

But:

function test : boolean; begin test := false; end;

procedure test1; begin if test^; end;

generates the error "invalid type of argument of '^'"

function-identified-variable only appears on the rhs of the variable access production. The expression test^ seems lexically correct.

I know I am wrong. But where? How is function-identified-variable used?

I really can't understand 6.8.6.4 Function-Identified-Variables of the spec. It sounds like a function-identified-variable is the return value of a pointer function. Is test^ a pointer function?
