is there an equivalent to Excel MID Function in RS?

[jmills]

I am trying to replicate a MID function from an excel report, and cant seem to find anything that compares... does Report Studio have a similar function?

I am trying to find the 3rd character in a string
In excel, the function looks like: =MID(A1,3,1)

substr ( [dataitem],3,1)
