functions in F# .. why is it not compiling
- by Tanmoy
Hi,
I have written two versions of code. The first one works as expected and print "Hi". the second one gives me error that "block following this let is unfinished"
1st version
#light
let samplefn() =
let z = 2
let z = z * 2
printfn "hi"
samplefn()
2nd version
#light
let samplefn() =
let z = 2
let z = z * 2
samplefn()
Only difference is the printfn is absent in the second version. I am using Visual Studio 2010 as my IDE. I am very new to F# but this error seems very strange to me. I guess I am missing some very important concept. Please explain.
Edit: Also if I do it outside the function I get error even with the first version of code.
#light
let z = 2
let z = z * 2
printfn "Error: Duplicate definition of value z"
