Change Error in SubString Command behaviour?

Hi!
This gives "Error in SubString Command"
Let>Name=
MidStr>%Name%,6,3,Surename
Why? Shouldnt it just give Surename=
This forces me to make an if>Name= before the MidStr.
Can I override this beahviour in another way.

This Works:
Let>Name=John Doe
MidStr>%Name%,6,3,Surename

Because Name is zero length, so there's no 6th char.

But then this also should give an error:

Let>Name=J
MidStr>%Name%,6,3,Surename

But it doesnt!

It should be realy convenient if it was possible to configure it NOT to throw an error if the input variable is empty. Now I allways have to check so that it is not empty.

Thanks!

Fair point. They should be consistent. Noted.
