This is an inbuilt function function provided by PPWIZARD.
This function takes a single parameter and has no return code (on failure PPWIZARD will terminate). It must only be called while #Import is being processed.
You may pass one or more lines of data which will be written to the temporary file that pass one of an import generates.
To indicate the end of a line the Linefeed character (decimal 10) should be used the actual characters written to the file are determined by the /CrLf state.
For an example have a look at a complex import example.
