There is another manner by which formatted data can be stored in strings through use of the formline function which I described in this post.
The formline function is normally only used internally, allows for formats to be built and returned in the format output accumulator, $^A. Normally, the contents of this variable are outputted to the currently selected filehandle via the write command, but this variable, $^A, can be read and reset directly. From the previous node referenced:
Thus in this manner, through use of the formline function, both the output format and the subsequent formatted output can be retrieved and stored - This method is advantageous in that it can be employed with older installations of Perl. For further information see formline and perlform.
perl -e 'print+unpack("N",pack("B32","00000000000000000000000111010011")),"\n"' In reply to Re: Re: A format to "print" to variable?
