MATCH Function

The MATCH MPL function searches a character string for a delimiter character and assigns the substrings on either side of the delimiter to specified identifiers. The syntax for the MATCH function is:

%MATCH (id1 delimiter id2) (balanced-text)

Where

id1	is a valid identifier that is assigned text in balanced-text left of delimiter.
delimiter	is the first character to follow id1. Any non-macro character may be used (like a space or a comma).
id2	is a valid identifier that is assigned text in balanced-text right of delimiter.
balanced-text	specifies the text the MATCH function searches. It may contain macro calls.

The MATCH function searches balanced-text for the specified delimiter. When the delimiter is found, all characters to the left are assigned to id1 and all characters to the right are assigned to id2. If the delimiter is not found, the entire balanced-text string is assigned to id1 and the null string is assigned to id2.

       INC  R1
(next,list)(%list)
)
