Check out the October 1998 FoxPro Advisor, tips section. They mention that after November of this year, SYS(2015) will start generating a string that begins with a numeric character - invalid for cursor/table names. They suggest adding a character, such as "c" for cursor, to the beginning of value.

>This is a little off topic from your original question (which I think Nancy answered correctly), but if what you want is just the rightmost eight characters from SYS(2015), you would want to use SUBSTR(SYS(2015), 3, 8), or in fact just SUBSTR(SYS(2015), 3), but not (SUBSTR(SYS(2015), 3, 10). Although VFP5, and maybe other versions, lets us get away with using 10, IMHO it's not good programming practice to try to reference past the end of a string.
