Umm ... well ... yes and no.  The actual editing -- and thus the errors
-- can happen when you try to *use* the variable.  If you have a numeric
elementary field as a part of a group field (which is always assumed to
be alphanumeric), moving letters to the group field is permitted, but if
you then try to use the elementary field which is defined as numeric but
the storage of which now contains letters, you cause an abend.  (S0C7, I
would think.)

Implementor defined action, I believe.  Burroughs would allow.  Some strange reports could result <g>.
