How can I fetch number in string and convert it to double?

[aselim]

My string is like: ".... angle: 39.5 bla bla..." and stored in a buffer "Locals.rString".

I want to fetch "39.5" and convert it to double to store in "Locals.acıDegeri"

Thanks.

Put this in your statement step.

locals.str2=Mid(Locals.str,3,4),locals.num=Val(locals.str2)

Locals.str and locals.str2 are string type.

Locals.num is a number type

Locals.str has "sss49.2lll"

Mid(string, startIndex,<numChars>) 

You wrote startIndex=3 but it is not 3, actually I also don't know what it is because my string contains information from rs232 channel.

But converting part is true I think.

Do you know a expression which fetches after ":" character?

locals.num1=Find(Locals.str,":")

Use find function to get the location of :

Then use the mid function to extract the value
