# 38.3. Data Values in PL/Tcl

The argument values supplied to a PL/Tcl function's code are simply the input arguments converted to text form (just as if they had been displayed by a `SELECT` statement). Conversely, the `return` command will accept any string that is acceptable input format for the function's declared return type. So, within the PL/Tcl function, all values are just text strings.
