st: Using byable in a class member program

["Shrenik Shah" <nilradical@gmail.com>]

It seems that the byable option does not work correctly when used with
a class member program. (I am using Stata Version 8.2.)  For example,
if I try to create a test class:

version 8.2
class testclass {
}
program .test, byable(recall)
	if _by() {
		disp "by option worked"
	}
end

I find:

. .tc = .testclass.new

. sort index

. by index: .tc.test
unrecognized command:  .tc.test invalid command name
r(199);

However, if I define the program:

program test, byable(recall)
	if _by() {
		disp "by option worked"
	}
end

I obtain

. by index: test:

------------------------------------------------------------------------------------------------------------------------
-> index = 0
by option worked

------------------------------------------------------------------------------------------------------------------------
-> index = 2
by option worked

------------------------------------------------------------------------------------------------------------------------
-> index = 3
by option worked

------------------------------------------------------------------------------------------------------------------------
-> index = 5
by option worked

------------------------------------------------------------------------------------------------------------------------
-> index = 13
by option worked

------------------------------------------------------------------------------------------------------------------------
-> index = 26
by option worked

Is there some way to use the by option successfully within a class
member program?

Thanks,
Shrenik
