If the OUTPUT JCL or the sysout DD statement contains a FLASH parameter, JES prints with the forms overlay the number of copies specified in one of the following:

• COPIES=nnn, if the FLASH count is larger than nnn. For example, if COPIES=10 and FLASH=(LTHD,12) JES prints 10 copies, all with the forms overlay.
• The sum of the group-values specified in the COPIES parameter, if the FLASH count is larger than the sum. For example, if COPIES=(,(2,3,4) and FLASH=(LTHD,12) JES prints nine copies in groups, all with the forms overlay.
• The count subparameter in the FLASH parameter, if the FLASH count is smaller than nnn or the sum from the COPIES parameter. For example, if COPIES=10 and FLASH=(LTHD,7) JES prints seven copies with the forms overlay and three copies without.
