PRFCOPY is an XEDIT macro extending the power of the PREFIX commands COPY and MOVE. The main purposes or PRFCOPY are:
- copy & move of lines between files
- insert of same line(s) in multiple places of a file
- collect multiple lines before inserting in a file
- work in columns (with OVERLAY, REPLACE and INSERT)
The basic commands created by PRFCOPY are very easy to use and to remember:
KM, KMM, KC, KCC, KF, KP
(the same as standard XEDIT PREFIX commands, prefixed with a 'K')
(but you can define your own synonyms)
But there are more commands, such as
- KB
- to indicate a rectangular area to copy
- KKF
- to insert the lines, but keep them in the GLOBAMV stack
- KO
- to overlay the lines onto existing lines
- KW
- to copy one or a few words
- ..
- and many more
PRFCOPY Version 4.1 highlights 27 March 1998
With version 4.1, all PRFCOPY commands can be called from XEDIT's command line. And, when the cusror is in the filearea, they use the cursor line as starting point instead of XEDIT's current line.
This makes PRFCOPY very useful when running with PREFIX OFF (such as in PEEK).
PRFCOPY Version 4.1.A highlights 23 March 1999
Avoid a "TAREGT NOT FOUND" message when a PRFCOPY Prefix command is cleared.
PRFCOPY Version 4.2 changes 8 September 2000
The maximum line length supported by the CMS STACK and GLOBALV is 255, hence PRFCOPY's HELPfile tells that it can only handle lines up to 255 chars.
With V4.2, PRFCOPY displays an error message when lines are truncated while added to the stack, and -for the KM(M) command- the lines will not be deleted in case of truncation.
PRFCOPY Version 4.2.a changes 26 March 2002
A nasty bug was discovered (and fixed) in this -already old- code:
When using KMM and some lines are excluded in
the KMM range, PRFCOPY removed more lines than it placed in the stack.

20A1 V2K033 3390-3 3990-6 2 3600 12 0.0 12 00023
In the above example, the buggy PRFCOPY places three lines in the PRFCOPY
stack (as expected), but it removes 5 lines:
line 15, 18 and 19 (as expected), but also line 20 and 21.
PRFCOPY Version 4.2.b changes 2 April 2002
When KM or KMM commands cause the delete of XEDIT's current line, a target not found message was displayed.PRFCOPY Version 4.2.c changes 12 June 2002
No code has been changed, only one typing error in this document has been corrected. A few lines earlier I wrote:but it removes 5 lines: line 14, 18 and 19 (as expected), but also line 20 and 21.instead of
but it removes 5 lines: line 15, 18 and 19 (as expected), but also line 20 and 21.
PRFCOPY Version 4.2.d changes 28 May 2004
Due to demand, PRFCOPY is also packaged as a ZIP file.
PRFCOPY Version 4.2.e changes 7 Feb 2006
Avoid loop if issuing 'PRFCOPY' (to define synonyms) with pending KC (and alike) commands and excluded lines.
