You can use the LIMIT keyword to stop an unsuccessful search from reaching the

end of a procedure or function, or from wrapping around to the beginning of a

procedure or function. This stops a search from finding a label with the same

name as the target label elsewhere in the procedure or function. If you specify the

LIMIT keyword,

limit-expr

must be either a constant or an expression that

equates to a constant.

If no label in the NCL procedure matches the value of

limit-expr

, a compilation

error results.

MATCH

specifies the comparison to be performed between the label being searched for and

the statement labels. By default, NCL expects an exact match, both in length and

in value. MATCH has the following qualifiers:

Note In the following comparisons, the collating sequence for sorting ASCII characters is used. In general,

numerals sort before uppercase letters, which sort before lowercase letters.

specifies that the target label is the first label found that is matched by a subset

of initial letters of the supplied label. This is sometimes referred to as generic

equality. For generic equality, NCL considers labels equal though they differ

in length.

specifies that the target label is the first label found with a value that is greater

than or equal to the supplied label.

specifies that the target label is the first label found with a value that is greater

than the supplied label.

specifies that the target label is the first label found with a value that is less

than or equal to the supplied label.

specifies that the target label is the first label found with a value that is less

than the supplied label.

specifies that the target label is the first label found that is not matched by a

subset of the initial letters of the supplied label. See EQ.
