If your goal is to use SCAN function with consecutive delimiters as in
INFILE option DSD there is an option for that.
m or M specifies that multiple consecutive delimiters, and delimiters
at the beginning or end of the string argument, refer to words that
have a length of zero. If the M modifier is not specified, then
multiple consecutive delimiters are treated as one delimiter, and
delimiters at the beginning or end of the string argument are ignored.
