reading a "counter" file and incrementing based on # in file.
I would like to have a script open a file (the file will only have a single
number in it). If it sees a 1 or 2 it should increment the number by 1 - a 1 becomes a 2 2 becomes a 3. If it sees a 3 it should reset to 0. Any help would be greatly appreciated. On May 1, 4:51 pm, mjm <m***@discussions.microsoft.com> wrote:

Use at you own risk sFilename = "X:\Somewhere\somename.txt" set fso = createobject("scripting.filesystemobject") n = cSng(fso.opentextfile(sFilename , 1).readall) if n < 3 then n = n+1 else n = 0 end if fso.opentextfile(sFilename , 2, true).write n Tom Lavedas ========== http://members.cox.net/tglbatch/wsh/

If zero should be incremented to 1, that is what our solutions do, but perhaps it is supposed to stay at zero. Same if the number is already greater than 3, it will keep incrementing forever. /Al

I specifically set the test to handle >3, but assumed it should be reset. Your solution does the same, I believe. Neither of our approaches address numbers less than zero, as you stated. The other problem I recognized and chose not to address is if the file contains non-numeric data. General error handling just seemed to be outside of the scope of the request.
