Is it possible to call a function whose name is stored in a string in vbscript?

Question

i am trying to write a script in qtp like this

Public Function sayhi

msgbox "hi"

end

Dim level0

dim count1
 count1 = DataTable.GetSheet("Action1").GetRowCount
msgBox  count1

For counterVariable = 1 to count1
    functionname =  DataTable.value("methodnames","Action1")
    call functionname
    DataTable.GetSheet("Action1").SetCurrentRow(counterVariable)
Next

assume functionname is going to have a value say "sayhi". Can i use that value to call the function ? like i did in the code "call functionname".

I know it is not working but how to do such call ?

Answer 1

Option Explicit 

function abc(a)
  MsgBox a
End function

dim run : run = "abc ""Hallo"""
execute run

The execute method can do this

Public Function sayhi

msgbox "hi"

end

Dim level0

dim count1
 count1 = DataTable.GetSheet("Action1").GetRowCount
msgBox  count1

For counterVariable = 1 to count1
    functionname = "call " &  DataTable.value("methodnames","Action1")
    execute functionname
    DataTable.GetSheet("Action1").SetCurrentRow(counterVariable)
Next

will call sayhi if its in the datatable.
