Re: [netrexx-pipelines] Migrate OS/2 pipelines to NetRexx Pipes

[J L. T. <jlt...@ma...>]

Jeff,
	In a post to oor...@li..., René provided a sample pipeline to 
process z/OS SMF records using the nrx specs stage.  I thought you might like to be aware 
of another feature of the CMS specs stage that could be incorporated into nrx specs, so 
I'm sending it to you as well.

	I see that in this pipeline you use reverse with specs to trim trailing parts of your 
records.  I understand that the nrx specs stage does not yet completely emulate the CMS 
specs stage, but I hope that as it is improved it will fully support CMS-type inputRange 
notation.
	In CMS/TSO Pipelines, Author's Edition, pp. 165, 166 we see that
|	"An inputRange can contain a negative number; this specifies that the count is from the
| end of the record rather than from the beginning:
|	word -2 1
|	The general form of a range consists of two numbers separated a semicolon. Thus, there
| is a third idiom to refer to the entire record: 1;-1. When both numbers are positive,
| there is no difference between using semicolon and using a hyphen to delimit the 
numbers.  When the two numbers have the same sign, the first number must be less than or 
equal to the second one; it is an error to specify an ending column that is before the 
beginning one.  (Recall that -2 is less than -1.) When the numbers have different signs, 
a null input field is used when the beginning position is after the end position:
|	word 2;-2    1

	Thus, your pipeline could eventually use
|    :
| | specs 7;-2 1
|    :
| | specs 77;-10 1
|    :
