I did see a & b had a pointer address allocated. It looked like a normal pointer address range. I’ll try allocating 10 bytes to a later and see what happens.

But I wonder if the problem is due to where this data is stored and trying to copy b to a results in an attempt to write to protected memory? Have you tried allocating 10 bytes of memory to 'a' and then using StrCopy? Have you run the debugger and checked where the PChars 'a' and 'b' are pointing to before StrCopy? -------- Original message -------- From: Ross Levis <r...@stationplaylist.com> Date: To: 'NZ Borland Developers Group - Delphi List' <delphi@listserver.123.net.nz> Subject: Re: [DUG] StrCopy problem Doesn’t really help. a := 'abcdefghi' does allocate 9 bytes of RAM. I can access a and b after it is assigned. The problem is StrCopy crashes. I would expect “a” to have the same string as b once this is executed. Ross.
