Dear GPC-ers,
Upon including a range checking directive in the program
program test1; {$R+} const nmax = 6; type nrange = 1..nmax; var n : nrange; begin read(n); writeln(n); end.
and compiling with
gpc --borland-pascal test1.p
the compiler answers:
test1.p:2: warning: unknown compiler directive `r+'
My questions: (i) In the gpc manual on p. I read ... "all of BP compiler directives are supported by GPC..." {$R+} is one of them. Why the reaction above?
(ii) is there any possibility of range checking with GPC? I could not find the expression "range checking" in the manual text.
Thanks in advance, K. Veselic.
