This is an inbuilt function function provided by PPWIZARD.
This routine takes a single parameter which is the name of the file which you wish to display in a "reading" progress message.
This function is useful where you read a file from rexx code as PPWIZARD otherwise would not know of it and so can't display its own progress message.
To be consistant with what PPWIZARD does you should use this function without passing any parameter after the file creation has been completed, this will output a "reading" message for the current input file.
You can use the /Reading switch to alter how the message looks.
