A counterstring is a graduated string of arbitrary length. No matter where you are in the string, you always know the character position. This comes in handy when you are pasting huge strings into fields and they get truncated at a certain point. You want to know how many characters that is.
Here is a 35 character counterstring:
2*4*6*8*11*14*17*20*23*26*29*32*35*
Each asterisk in the string occurs at a position specified by the immediately preceding number. Thus, the asterisk following the 29 is the 29th character in that string. So, you can chop the end of the string anywhere, and you know exactly where it was cut. Without having to count, you know that the string “2*4*6*8*11*14*17*2″ has exactly 18 characters in it. This saves some effort when you’re dealing with a half million characters. I pasted a 4000 character counterstring into the address field of Explorer and it was truncated at “2045*20″, meaning that 2047 characters were pasted.
