Hi Leslie,

Yes, it seems that ’specs’ keeps growing and growing. The good news is that in 
our implementation Jeff did a separate part for inputRange and if it works 
there, it should work everywhere.
For clarity, I did not try this because at the moment, I did what I would do in 
Rexx.

[J Leslie Turriff]

René,
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;-21

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

Thank you. I too would not want this to hold up progress towards v5.0

Greetings Harmander,

Personally since Classic Rexx on say OS/2 is so antiquated these days, I think 
the line has long been crossed for quickly executing untouched Classic Rexx 
programs on current ooRexx.

At least that is my vote... when porting Classic Rexx to ooRexx, expect some 
code changes to best optimize for ooRexx.

I am thankful,

Terry,
One issue which came up in this context a long while back was that at some stage in the development of v5.0, the classic Rexx file input statements linein, charin 'had a performance hit' (they became 
much slower than their ooRexx counterparts).


That problem doesn't appear to have been as yet addressed (I had checked a few 
months ago).

I can't say if this issue is a 'showstopper'.

Terry,
One issue which came up in this context a long while back was that at
some stage in the development of v5.0, the classic Rexx file input
statements linein, charin 'had a performance hit' (they became much slower
than their ooRexx counterparts).

That problem doesn't appear to have been as yet addressed (I had checked
a few months ago).

I can't say if this issue is a 'showstopper'.

It would be nice if there was documented support for GUI on non-Windows

any of the Rexx ncurses add-ons)...
