>OK thanks.

From the manual:

"SYS(3) may return a non-unique name when issued successionally on a fast computer. Use SUBSTR(SYS(2015), 3, 10) to create unique, legal eight character file name."

"The name that SYS(2015) returns is created from the system date and system time. Calling SYS(2015) more than once during the same millisecond interval will return a unique character string."

Additional notes:

sys(2015) is 10 characters instead of 8. This may affect some of your procedures.

sys(2015) always starts with a character. Not so sys(3).
