Infile usage/replacement

[Paul E. Johnson]

I came across an older swarm app that used InFile in this way. The file
that is retrieved by InFile has a word, then two numbers, and the agents
are created by getting the word, translating that to a class name, and
then getting the numbers for IVARS, and it repeats until all the lines
of the infile are used up.  This uses some objc things I've not seen
before, so in case anybody reading is a learner like me, here it is:


   aFileObj = [InFile create: [self getZone] setName: "trader.setup"]; 

   while ([aFileObj getWord: tClassStr] != 0) 
    {
    [aFileObj getInt: (int *) &rEndow];
    [aFileObj getInt: (int *) &rlEndow];
    tClass = objc_lookup_class (tClassStr); 
    numTraders++;
    sprintf (objNamStr, "%s%d", tClassStr, numTraders);

    aNameObj = [UName create:[self getZone] setBaseName: objNamStr];

    aTrader = [(id) tClass createBegin: [self getZone]];
    [aTrader setMktMaker: mktMaker];
    [aTrader setMktStats: mktStats];
    [aTrader setLiqMean: liqMean liqVar: liqVar];
    [aTrader setDiagLevel: diagLevel];
    [aTrader setTraderName: (char *) [aNameObj getNewName]];
    [aTrader setEndow: rEndow : rlEndow]; 
    aTrader = [aTrader createEnd];

      // Add to all proper lists
    [traderList addLast: aTrader];
  }

I understand the deprecation of Swarm's InFile. How would you replace
this functionality?
