>I need the fastest way to verify for similar characters in a variable. For example, I need to take action when I see a value such as "aaaaaaaa" or "bbbbbbbbbb". What's the best way to accomplish that?

lcStr = "bbbbbbbbbb"
IF LEN( STRTRAN(lcStr, LEFT(lcStr,1), "")) = 0
  * All characters in the string are the same
ENDIF
