The RPN calculations work only with numbers. Since the RRD can only hold numbers anyway, there is no need for it to handle strings.

I did some tests using numbers and it worked, but when I try with strings, it gives an error.."ERROR: invalid rpn expression in:" for example.. assuming a=10; a,10,EQ,1,0,IF .. it works...returns 1 ... but with strings: assuming a="test" a,test,EQ,1,0,IF .. it gives me the error message above... I guess I should use another boolean function .. different than EQ .. but I don't know how.. is there any way? thanks -- Att, Image removed by sender.
