Call subroutine by variable value

[gabba]

Hi,
is it possible to call a subroutine (or a function) using variable name?

Sub a()
Response.write("sub a")
End sub

Sub b()
Response.write("sub b")
End sub

Sub c()
Response.write("sub c")
End sub

Dim subname
subname = "b"
**call subname**
'does exist something like this? or something like the javascript 'eval' ?

Thanks..

"Eval" exists in VBScript and is described as:
"Evaluates an expression and returns the result."

"Execute" will do what you want:
"Executes one or more specified statements."

Option Explicit
Const subname = "b"
Execute subname
Sub b()
Response.write("sub b")
End sub

Or you could use:
Const subname = "b()"

See the VBScript "Execute" statement as a last resort...

You could also use classes (though VBSciprt has limited support for this)
depending on what is the overall goal.

"Eval" exists in VBScript and is described as:
"Evaluates an expression and returns the result."

"Execute" will do what you want:
"Executes one or more specified statements."

Perfect, really thank you.
this is what i'm lookink for.

I mentioned the javascript command eval() cause it's exactly the VbScript
Execute().

so...now I know that javascript eval and vbscript eval are false friends ;)

And all three are evil.

Using Eval poses a significant security risk, so it is preferable to use
GetRef in this situation.

Option Explicit

Sub a()
WScript.Echo "sub a"
End Sub

Dim subname
subname = "a"

Dim s
Set s = GetRef(subname)
s
