I understand the concept.

Easy, since you know what you are looking for, throw away everything else. Then
make the remaining items into the form you'd like, regardless of what they are,
then
pass that to your input.

user: a,B,c
program: upcase alphabet, delete all non-alphanumeric(,";;'<>,./?, spaces, etc)

user: 1 2 3
program: upcase alphabet, delete all non-alphanumeric(,";;'<>,./?, spaces, etc)

user: a 5, X
program: upcase alphabet, delete all non-alphanumeric(,";;'<>,./?, spaces, etc)

UNTESTED ( translated to Eu from mirc )

for loop = 1 to length(input) do
   inputseg = mid(input,loop,1)
   intermediatetemp = findtok(" A B C 1 2 3  ", inputseg ,1,32)
   if ( intermediatetemp != 0 ) then
-- assuming a=1 b=2 and c=3, if not, then use other id#'s or something in the
following
line,, i'm just parsing the possible random input from user.
NeedToDo  =  gettok(" routineid1 routineid2 routineid3 routineid1
       routineid2
routineid3 " , intermediatetemp ,32)
-- here, do something with NeedToDo, save it, exec it, display it, or
       something.
-- Robert, this would be a great place for a "gosub(sequence
SomeValidRoutineName)"
 or an "exec(sequence SomeVariableTheProgramMade)",
something that makes the routineid() setup/calls transparently to the
programmer.
   end if
end for


Kat,
loving those string routines in strtok.e
