RE: [sqr-users] RAT in sqr - search char string for first pos of charstarting from the right?

["Bob Stone" <bstone@fastenal.com>]

Assuming you have a good way to search from left to right, you could
search for the LAST occurance from left to right.  

pardon my pseudocode - it's been a long day and syntax makes my brain
hurt

let #i = 1
let #lastpos = 0

While i < length($string)
  if substr($string) = '\'
    let #lastpos = #i
  end-if
  add 1 to #i
end-while


For that matter, the same while loop could work backwards from
length($string) to 1, and assign #lastpos and break if it finds the
character.  Don't forget to add code incase there aren't any '\' in the
string.

Hi All,

How do I search a char string for the first occurance of a character
going
from right to left?

Example

c:\dir1\dir2\file.txt

How do I find the position of the THIRD \ (answer would be 12).

Thanks, Paul
