IF command with strings

Hello everybody...

I would like to know how to use the IF command to check string variables, to do something like this:

string Svar

IF ( Svar=="ABC" )
      // do this
Else
     // do that
EndIf


I know it is a silly question, and should have a simple solution.. but I've been stuck with this for a long while, and I have found just examples with numeric variables.

Thanks

Andre
you need

string str
if (cmpstr(str, "ABC") == 0)
  //do this
else
   //do this
endif


I would not use "svar" as string name, because SVAR is used as global string declaration.

yes.. it worked!
The name of the variable was just an example.. but well reminded!

Thanks you all!

Also consider stringmatch for this use. The help page for stringmatch lists a few other useful string handling functions.

An alternative construction is illustrated here.

Function TestString(tstr)
     string tstr

     strswitch(tstr)
          case "Hello":
              print "got hello"
              break
          case "Goodbye":
              print "ciao"
              break
          default:
              print "Input Hello or Goodbye only"
              break
     endswitch
     return 0
end

Another nice function for this is GrepString,
which would allow you to match all of "abc1", "abc2", "abc3" using "abc"
(or even "abc\d{1}")
