thanks Ron, I hadn’t thought about class variables.
sincerely,
Joe.

Hi Joe,
I'm not sure in what context you mean. Why wouldn't you run this in the #initialize method?
JoeAccountingParser class>>configure InPath := '/Users/jja/Desktop/accountingfiles/'. OutPath := '/Users/jja/Desktop/accountingfiles processed/'.
JoeAccountingParser >>initialize self class configure. fileParser := FileParser new. fileParser inPath: self class InPath. fileParser outPath: self class OutPath.

JoeAccountingParser process: aFile fileParser readThis: aFile. fileParser process. fileParser write.
This is a bit refactored and it uses the configure method I recommend to you earlier. This configure method could be anything including a method to read an external file for details.
Solutions like a factory method pattern come to mind if you don't want to use #initialize.
JoeAccountingParser class >> process: aFile from: inPath to: outPath
There is also Behavior #startUp and #shutDown on the class side.
See Smalltalk #addToStartUpList: #addToShutDownList:
These fire when an image is started or shutdown.
I think a bit more explanation of what problem you are having is needed.
All the best,
Ron Teitelbaum

Greetings,
My object needs to have some variables set before it can run the
initialize
method and also it needs to have run an exit method.
f := FileParser new. f inPath: '/Users/jja/Desktop/accountingfiles/'. f readThis: 'rei mastercard.csv'. f process f outPath: '/Users/jja/Desktop/accountingfiles processed/'. f write.
Is there a better way to do this?
Sincerely,
Joe.
