RE: [Gm2] Returning a string constant

[Breeden, Thomas (tmb)]

Hi all,

Actually, in ISO Standard Modula-2, it is legal.

One of the changes made from Wirth's definition of the language is that 
functions can
return structured types.

I tried the test program out in my copy of the late, lamented, Stony Brook 
compiler and
it compiled and ran perfectly.

I'm pretty much in sympathy with all the arguments against, but I feel that it 
would be
better for M2 if GM2 did implement the ISO standard.
