FCB

Specifies the name of the page definition to be used in formatting a print data set. PSF adds the system prefix P1 to the forms control buffer (FCB) name you specify and uses it for the page definition.

You can specify the FCB parameter in a DD statement or in an OUTPUT statement, as follows:

FCB=pdefname

The value is:

pdefname

Specifies one to four alphanumeric characters for the page definition name. Do not use a P1 prefix.

When you are using the FCB parameter, remember:

• If you specify the parameter in both a DD statement and an OUTPUT statement, PSF uses the parameter in the DD statement.
• If both an FCB parameter and a PAGEDEF parameter are coded in your JCL, PSF ignores the FCB parameter. See PAGEDEF.
• If you are using Line Mode Migration and an FCB parameter and a FORMLEN parameter are coded in your JCL, PSF uses the FORMLEN value and ignores the FCB parameter. See FORMLEN. For more information about Line Mode Migration, see PSF for z/OS: Customization.
• Because the maximum length of a PAGEDEF parameter is six characters and the maximum length of an FCB parameter is four characters, you cannot use the FCB parameter to specify all page definitions. IBM® recommends that you use the PAGEDEF parameter when you do not want any changes in the JCL and you are not converting jobs from line printers.

See Specifying a page definition for examples of using the FCB parameter to specify page definitions.
