[J3] US21 INT for enum type

[Malcolm Cohen]

Hi John,

 

> I have not found it said anywhere that varables of enum type are integers.

 

Correct, they are of enum type, not integer type.

 

> However, INT does not provide conversion from enum type. Is this a mistake?

 

Yes, that is an omission. Looking at the specs, (21-110r1), it does not say that INT is available for enum type, but in several places (in particular, spec (I), for i/o) – implies that we were expecting it to be available.

 

I will write a paper. Thanks for noticing this.

 

Cheers,
