Use constants within structure

it might be good to allow the VALUE attribute in structures that did not consist solely of fields with the VALUE attribute. So allow

dcl 1 mystr,
2 ...,
2 sex char(1),
3 male char(1) value('M'),
3 female char(1) value('F'),
2 ...

if mystr.sex = mystr.sex.male then ....

    Just Wondering: if named const are part of a struct, how will the memory layout look like? Will the const members just be removed?

    This would be useful for the reasons described, but it will also be a little bit tricky to implement if we don't design it right

    I once asked why consts cannot be member of struct and got the answer that consts are replaced at compiletime (similar to preprocessor variables) and therefore reside in completely different memory than structs (correct me if i remember something wrong).
    My approach was to have consts separated from variables, but grouped in a struct (mainly to allow a better, structured naming "sex_c.male").
    Your approach - having consts and vars mixed - goes even further!
    Beside that i like the idea much!
