Change command append blanks

[Lars Höglund]

Can somebody explain why this command append blanks

 

Command ===> c all '"' ''                                     Scroll ===> CSR 

****** ***************************** Top of Data ******************************

=COLS> ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--

000001 "AAAAAAAA"!"BBBBBBBBBBBBBBBBBBBB  "!1.!1.!1.!"CCCCCC  "!"DDDD"         

****** **************************** Bottom of Data ****************************

 

Result

 

Command ===>                                                  Scroll ===> CSR 

****** ***************************** Top of Data ******************************

=COLS> ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--

==CHG> AAAAAAAA!BBBBBBBBBBBBBBBBBBBB     !1.!1.!1.!CCCCCC    !DDDD            

****** **************************** Bottom of Data ****************************

 

Shouldn’t the result be

 

Command ===>                                                  Scroll ===> CSR 

****** ***************************** Top of Data ******************************

=COLS> ----+----1----+----2----+----3----+----4----+----5----+----6----+----7--

000001 AAAAAAAA!BBBBBBBBBBBBBBBBBBBB  !1.!1.!1.!CCCCCC  !DDDD

Lars,
   Refer to the following in the ISPF Edit and Edit Macro manual:
 
Effect of CHANGE command on column-dependent data
Column-dependent data is groups of nonblank source data separated by two or more blanks, such as a
table. When you use CHANGE to change column-dependent data, ISPF attempts to maintain positional
relationships. For instance, if you change a long word to a short word, the editor pads the short word with
blanks. This padding maintains the column position of any data to the right of the change by preventing it
from shifting left.
When only one blank separates words, as in most text data, padding does not occur. Changing a long word
to a short word causes data to the right of the change to shift left.


Your data has multiple spaces between the actual data so it fits the Column-dependant data definition above.  Hence Edit maintained the
column position.

- as explained in another reply. To achieve what you wanted, you could
first change all spaces in the lines concerned to some character not in
the current data, then do your change, then reverse the first change.

Jeremy Nicoll - my opinions are my own.

Ummm... Suppose you have 3 consecutive blanks, " " and you change them
To "¾¾¾". Does changing them back proceed from left to right, so at
some point you have " ¾". That should trigger the column-aware behavior,
so changing the third "¾" lets it collapse to nothing.

Thanks, missed that.

 

Then I have to use Sort or why not a Rexx

You can use REXX. I always run my REXX "remove character" routine and I usually write to a new dataset (temp) so that I am not destructive, I pass the character that I want to change from and to and the output dataset.

[Lars Höglund]

To make it “quick” I’ll use Sort

 

OPTION COPY                       

INREC FINDREP=(INOUT=(C'"',C''))

Gah! You're clearly more awake than I am.

[Bob Bridges]

Well, when doing one of these "change char", "change back" operations you always have to choose your temporary char with care, to be sure it isn't already in there somewhere. If it's a long enough dataset that I can't be confident I'll pick something unique, I usually go for a hex 0 or a hex 1 or something like that.
