Hi

I have a problem with the new Perl release which I did not have with the 5.6.1 release.

With this mail I will send a perl script and input file. If I run this against the 5.8.7 release I get the error

Start Verwerking... Modification of a read-only value attempted at ./lgp2000.pl line 85\, \ line 14.

The 5.6.1. release runs fine.

In line 14 there is a '% n' if we change the '% 'into 'percent' or the 'n' into 'ernaar' then it is ok.

14 58000013596900529Kendrion heeft in het eerste kwartaal van 2005 een nett owinst behaald van 3\,6 mln euro. De omzet liep op van 133\,7 mln euro naar 146\,2 mln euro. Het bedrijfsresultaat daalde met 10% n ar 6\,9 mln euro. (FD10052005)

Are you able to advise me what to do to solve this? \<\<LGP2000.DAT>>

With kind regards\,

I think that if you correct this line of your script from

  printf $filFileHandle $strInput;

to

  print $filFileHandle $strInput;

you script will work. The author of the script fell into the trap mentioned in the documentation for printf​:

  Don't fall into the trap of using a printf when a simple   print would do. The print is more efficient and less   error prone.

However\, it looks like the error reporting for printf with a %n format and no argument could be more helpful. The value it's trying to modify doesn't exist\, rather than merely being read-only​:

$ perl -we 'printf "%n"' Modification of a read-only value attempted at -e line 1.

Thanks for the quick response. It works fine now. So you can close the call I think.
