Challenge for NetRexx

[Robert L Hamilton]

This same function has been written in several languages. . . Not in NetRexx that I know of.

/* Some original comments have been marked with REXX comments tags

Let’s take a look at an example program that uses some of the program flow which was discussed in this chapter. The example program simply makes use of an external text file to manage a list of players on a sports team. You will see how to follow proper program structure and use spacing effectively in this example. You will also see file utilization in action, along with utilization of the raw_input() function.  */

/*Listing 3-26. # import os module  */.

enter_player = ''

# Enter a loop to enter inforation from keyboard -- NB: obviously 'information'

    # If the file exists, then allow us to manage it, otherwise force creation.

Hello Robert,
   1.) Would you mind to tell us *in which Languge* yoiur included program *is written* ?
   2.) Could you send me, please the players.txt file?
   3.) Then I dould send you the NetRexx Version back using (using my RexxFile and RexxMsg methods, which are very similar, by the way!)

Kind regards, from Vienna,
Thomas.

It looks like the Python example that can be found here: http://www.jython.org/jythonbook/en/1.0/OpsExpressPF.html.

Hugh,
   thanks a lot for the hint.

Never looke at Python etc up for now (to many other still opened issues).

Bob, Do you have a 'players.txt'  file as a startup ?
Thomas.
