We have been using SYS(2015) for years without any problem. No delay required.

FILE1=RIGHT(SYS(2015),8)+".TXT
REPORT FORM MyReport TO (FILE1) NOCONSOLE
MODI COMM (FILE1) WINDOW W_SHOW NOEDIT
...
ERASE (FILE1)

Try this in a small program. You will never get a duplicate even on the fastest computer.

FILE1=RIGHT(SYS(2015),8)+".TXT
FILE2=RIGHT(SYS(2015),8)+".TXT
FILE3=RIGHT(SYS(2015),8)+".TXT
FILE4=RIGHT(SYS(2015),8)+".TXT
FILE5=RIGHT(SYS(2015),8)+".TXT
