How to assign a variable its width/vector

samd has asked for the wisdom of the Perl Monks concerning the following question:

I am trying to design a buffer(linebuffer of size 32 bytes)which compares its size(say 32 bytes) with every incoming hexadecimal addresses from an input file. After comparing the size of the buffer with the size of the instruction, i want to determine whether the incoming instrution fits into the buffer or not.

The input file has the hexadecimal addresses used for comparison that looks like below.

0x405d75  
0x4035f7  
0x4035f8  
0x4035fb  
0x4035fc  
0x405d7a  
0x405d81

I am trying to make the size comparison between the buffer and these input addresses by calculating the length of these addresses using the length($_) along with the pragma use bytes but i am unable to declare the buffer size as 32 bytes. i am not able to use the same pragma on the buffer size to display a hexadecmal number interms of bytes.

Thanks in advance!

Read I know what I mean. Why don't you? and consider how your question might look to someone who has no idea what you are talking about. Perl is the programming world's equivalent of English	[reply]

i dont understand what you are trying to infer from that question. I am not trying to infer anything :) Your question as posted is unclear to me; esp your talk of the bytes pragma and vectors and widths ... Have you read bytes? If you could post some code in the style of perlintro , where you compare whatever value you have, with whatever value you expect, and show where you try to declare the "buffer size", it would clarify your question greatly for me	[reply]
