The latter seems to cater to the expectations of PL/I or some other
language.
Catenation with || is PL/I and other languages.
But I confess to an obsession with performance. Function call/return

Catenation can be costly, because either or both operands need to be
moved.
In XPL, both operands are moved, except when the first operand
is at the top of the free area.
so I'll use:
PARSE VAR A . . X .
rather than (the sparser?):
X = SUBWORD( A, 3 )
