What does this mean? How can I read this in plain english?
Thanks in advance. :)
Regards,
Looks like a hex dump that you're showing there. Two hex digits represent the contents of one byte. Depending on your compiler, integer may be 2 or 4 bytes or whatever (16 bit vs. 32 bit vs. 64 bit of whatever the size of integer may be).
The packed keyword is to tell the compiler to squeeze the bits of a array as close together as possible. For example, ASCII chars are only 7 bits long, and if your byte is 8 bits long (on the original machine that Pascal was implemented in, it was something other than 8 bits to the byte), you could use the unused bits of the byte to store part of the next character in the array. Thus, if you squeezed all the bits together, you might save a few bytes in an array. IIRC Turbo Pascal ignored the packed keyword altogether and was perfectly happy wasting the unused bit per byte, so each character in an array would occupy precisely one byte, and it would leave the high bit of each byte unused. So, even if you have the same data in a packed array, different compilers may give you a different hex dump depending on whether they choose to obey or ignore the packed keyword for the array.
