The content for these slides will come from the accumulators.odt chapter of the P2J Conversion Reference.

The slides filename in Bazaar (in the p2j_training/developer1/ project) should be accumulators.odp.

Please note that I have not yet had a chance to review this chapter, so if you see something that looks questionable, please ask about it. Constantin will be able to answer questions as well; he is the author of the chapter and is largely responsible for the implementation of the accumulator support in P2J.

Following are some of the texts from the accumulators.odt document that should be reviewed:

page1: "although in some terms this simplification might indicated that writing ..." ->
       "although in some terms this simplification might indicate that writing ..." 
page1: "complex expressions, which combine variables, constants and field." ->
       "complex expressions, which combine variables, constants and a field." (or "fields")
page7: "Countccumulator()" ->
       "CountAccumulator()" 
page7: "When a complex expression is involved, it will be ignored, as it doesn't need to evaluate it." ->
       "When a complex expression is involved, it will be ignored, as it doesn't need to be evaluated." 
page9: "the other statements get converter." ->
       "the other statements get converted." 
page18: "that each expression may have specified more than one aggregator" ->
        "that each expression may have more than one aggregator specified" 
page20: "the converted rules emit the ..." ->
        "the conversion rules emit the ..." (2 times)
page23: "Note how code is emitted only for the first ACCUMULATE statement." ->
        "Note how the code is emitted only for the first ACCUMULATE statement." 
page 34 (in the Syntax box): "ACCUMULATE" ->
                             "ACCUM" 
page 35: "AverageACcumulator" ->
         "AverageAccumulator" 
page 35: "these section will not " ->
         "this section will not" 
page 35 (Example 1): "Converted code" ->
                     "Conversion result" 
PAGE 39 (duplicate): "the accumulated result in the parent" ->
                     "" 
page 40: "This will the accumulator reset" ->
         "This reset the accumulator" 
page 43: "The difference between this and example #3" ->
         "The difference between this and example #2" 
page 46: "will be accumulated in all parent block which refer the same accumulator" ->
         "will be accumulated in all parent blocks which refer the same accumulator" 
page 48: "In this case, both MESSAGE statements will always display the accumulated result from block B2.  This is because," ->
         "Both MESSAGE statements will always display the accumulated result from block B2 since," 
page 50: "will set special some flags" ->
         "will set some special flags" 
page 50: "and it should accordingly" ->
         "and it should act accordingly" 
page 62: "can be used only as along as the procedure is executed" ->
         "can be used only as long as the procedure is executed" 

Please make all the changes suggested in the previous update, except the change for page 46 should be:

"will be accumulated in all parent block which refer the same accumulator" ->
"will be accumulated in all parent blocks which reference the same accumulator"
