Robin observed:
They are no substitute for
MVC A(L'B-1),B
MVC A(L'=C'...60-character literal...'),=C'...60-character literal...'
where the repeated typing is error-prone, and the need for continuations is
clumsy initially, and especially if the literal must be modified.
You wouldn't use that construct at all.
Certainly, the literal can be replaced by a named constant,
Indeed. But in any case, you'd use
MVC A,=C'...'
but many programmers like seeing the literal's contents where it's used.
See previous.
In any case, using the length of the second operand to determine the
transfer is risky, as John Walker noted, and is liable to error when code is
modified.
