Hello Dale,

    Responding to a post in the 4DOS area:

I'm not sure about 4NT, but with 4DOS, I use FFIND.

I don't know if you can apply my example to your requirements but here's
how I use it:

=== Cut Begin: SNIPPET.BTM ===
set xan=%@word[2,%@execstr[FFIND /k/m/r/t"node 1 (dialup), 1:342/806" %=
C:\Fd\FD.LOG]]

      iff "%xan" NE "Xanadu" then
        goto looper
      else
        call C:\4d\4b\TESTIME.BTM
      endiff
=== Cut End:   SNIPPET.BTM ===

I _WAS_ using the above snippet to synchronize my system clock to that of
my host (1:342/806) by searching my FrontDoor log file for the string
Xanadu.

My Testime.btm would then search the FrontDoor log file for the strings
"RTime" (Remote Time) and "LTime" (Local Time) and compare the values
following those two strings...

=== Cut Begin: TESTIME.BTM ===
.....
  set ret=%@time[%@word[6,%@execstr[FFIND /k/m/r/t"RTime" C:\Fd\FD.LOG]]]
  set lot=%@time[%@word[6,%@execstr[FFIND /k/m/r/t"LTime" C:\Fd\FD.LOG]]]
  set remot=%@maketime[%ret]
  set local=%@maketime[%lot]
.....
=== Cut End:   TESTIME.BTM ===

I hope that is of some help to you.

           Cheers ... Gerald
