management routines are pretty optimized?</FONT></DIV>

<DIV><FONT face=Arial size=2>You could consider instead using a tmemorystream

<DIV><FONT face=Arial size=2>Hi all</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I need a fast/efficient way of building a
string from data within a loop. The string is getting longer and
longer and therefore reallocating the whole string in memory every loop.
Each loop it gets a few words added, perhaps an average of 30
bytes.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I thought of doing a SetLength on the string
every 256 bytes or so, but I'm not sure of the best method
of moving the data into the correct position in the
string.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any suggestions?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Cheers,</FONT></DIV>
<DIV><FONT face=Arial size=2>Ross.</FONT></DIV>
