CVAFFILT supports partially-qualified data set names using single or double asterisk notation and the percent sign as shown in the following text:

• You can use a single asterisk to represent a single qualifier. For example, SYS1.*.LOAD designates any data set with three qualifiers, the first being SYS1, the second being any qualifier, and the third being LOAD.
• You can also use a single asterisk to represent zero or more unspecified characters. For example, LOAD.*LIB designates any data set having only two qualifiers, with LOAD being the first, and the second qualifier ending with the character string LIB (for example, LINKLIB). The asterisk can appear anywhere within the qualifier. You can use two single asterisks in the following way: LOAD.A*B*.LIB. CVAFFILT does not support the use of two or more single asterisks with any other character within a single qualifier (for example, LOAD.B**.LIB is not valid).
• A double asterisk represents a place holder for zero or more qualifiers. For example, SYS1.** designates any data set having SYS1 as its first or only qualifier.
• You can specify a percent sign (%) as part of a partially-qualified name. The percent sign designates any data set whose name matches the partially-qualified name, except for the single character in the position indicated by the percent sign. For example, SYS%.*.LOAD% designates any data set with three qualifiers, the first being any 4-character qualifier beginning with SYS, the second being any qualifier, and the third being any five character qualifier beginning with LOAD.
