Prints a string or a list of strings. Returns true if successful. FILEHANDLE may be a
scalar variable name, in which case the variable contains the name of or a reference to
the filehandle, thus introducing one level of indirection. (NOTE: If FILEHANDLE is a
variable and the next token is a term, it may be misinterpreted as an operator unless you
interpose a + or put parentheses around the arguments.) If FILEHANDLE is
omitted, prints by default to standard output (or to the last selected output channel--see
/select). If LIST is
also omitted, prints $_ to the currently selected output channel. To set the
default output channel to something other than STDOUT use the select operation. The
current value of $, (if any) is printed between each LIST item. The current
value of $\ (if any) is printed after the entire LIST has been printed.
Because print takes a LIST, anything in the LIST is evaluated in list context, and any
subroutine that you call will have one or more of its expressions evaluated in list
context. Also be careful not to follow the print keyword with a left parenthesis unless
you want the corresponding right parenthesis to terminate the arguments to the
print--interpose a + or put parentheses around all the arguments.
Note that if you're storing FILEHANDLES in an array or other expression, you will have
to use a block returning its value instead:
print { $files[$i] } "stuff\n";
print { $OK ? STDOUT : STDERR } "stuff\n";
