| Subject: | getline_hr_all dies silently when input field uses double-quotes |
Hi
Here is my output from running the attached 'text.csv.pl':
ron@zigzag:~$ perl text.csv.pl
Writing:
Input: <1One1>. Output: <1One1>
Input: <2"Two"2>. Output: <"2""Two""2">
Input: <3Three3>. Output: <3Three3>
Reading:
Line => 1One1.
ron@zigzag:~$
The " embedded and doubled in line 2 causes getline_hr_all to die
silently, so what the module writes can't be read.
Cheers
Ron
