Hi Sholmi
I am using write mode for file writing because filename with counter value
has assigned so there is no possibility of overwriting.

Amit,
Thank you for the quick response.
What i actually meant was the line number of the source-script file, that is
now being read (executed).
This is achieved (so i learned from the list) by the __LINE__ directive.
Thanks again.
Amit.

Hi Stewart,
Is there *anything* that might convince you to stop top-posting?
Let me put it another way: please stop top-posting.

NE__ is the source file line number where it is placed. For

print
__LINE__

will output '3'.
The built-in function caller() will return a list of three values - the package
name, file name, and file line number of the place where the current subroutine
was called. So

Just use $. To print current line number.

You should verify that unlink worked correctly:

Hi,

I am using the I am trying to figure out to pass my $exp to the

here is the error message
perldoc -> perlvar
$. is reset when the filehandle is closed, but not when an open
filehandle is reopened without an intervening close(). For more
details, see "I/O Operators" in perlop. Because <> never does an
explicit close, line numbers increase across ARGV files (but see
examples in eof).
Seems that I recall perl having a built in like awk's FNR that keeps
track of the current line number in each file. Zeros out on each new
file.
Like $. only goes to zero on each new file.
I know how to do that with code but wondered if perl already does it
thru some builtin.
