How can be find the location of procedure (function) in TCL. Under location I mean the source file in which it is declared.

I'm trying to read foreign source-code and can not find the declaration of a single procedure, example:

set MSISDNElement [regexp -all -inline {ISDN +[0-9]+} $Command]

if { $MSISDNElement != "" } {
    foreach elm $MSISDNElement {
        set MSISDNValue [list ISDN [getInternationalFormat [lindex $elm 1]]]
    }
}

set EptData [list [lindex $Command 1]]

InitEptData 3
foreach Element $EptData {
    SetEptData [lindex $Element 0] [lindex $Element 1]
}

For the functions InitEptData & SetEptData I can't find any declaration. Could someone familiar much more in deep with TCL, to explain how to solve that issue which I'm facing? Thanks in advance!
