Changing Function's Actions

[brett]

How would i make one function, for example Read(), but make that one find the response in an Instant Message, but if i call the function using Read(Command), it'll send it to the command run function, but if i call the function using Read(Path) It'll do the same actions but send the variable it creates to a different function based on the parameter.

Does anybody get this? it seems confusing.

UDF do not have optional parts though, so you can't call a function:

Read() ; as in blank

Read("Command")

Read("path")

you would have to call it like:

Read("")

Read("Command")

Read("path")

hope that wasn't confusing.

If a UDF is set up for 3 parameters, you need to use all 3 even if they are blank.

$year="2004"
three("Hi",$year,"")
; three("Hi",$year); this would error
; three() ; this will error

func three($x,$y,$z)
; code
endfunc

Error would be: Incorrect number of parameters in function call.
