The features and functions described in this chapter are considered
obsolete and should not be used by new programs. They're retained for
compatibility with past versions of Guile.
@deffn {Scheme Procedure} substring-move-left! str1 start1 end1 str2 start2
@deffnx {Scheme Procedure} substring-move-right! str1 start1 end1 str2 start2
These functions are aliases for @code{substring-move!} and calls to
them can simply be replaced by @code{substring-move!} (@pxref{String
Modification}.)
In the past, if @var{str1} and @var{str2} were the same string, it was
necessary to call @code{substring-move-left!} if the move was to the
left (@math{@var{start2} < @var{start1}}), or call
@code{substring-move-right!} if the move was to the right
(@math{@var{start2} > @var{start1}}). @code{substring-move!} is now
able to do both.
