//Here his where we'll store the concatenated strings
Char *packed;
//Here's where we want to add the null chars
Char *field1, *field2;
.

.
//Assume that field1+2 now have values asigned,
WITHOUT null-terminator
//+2 for null chars
packed = MemPtrNew(StrLen(field1) + StrLen(field2) +
2);
----------------- remove this -------------------
//Add 1 - presumably the null
StrNCat(packed, field1, StrLen(field1)+1);
//Here the string should be appended AFTER the null
char
StrCat(packed, field2);
--------------- change with this ---------------------
MemMove(packed,field1,StrLen(field1));
packed[ StrLen(field1) + 1 ] = 0;
MemMove(
(packed + StrLen(field1) + 1) ,
field2,
StrLen(field2));
packed[ StrLen(field1) + 1 + StrLen(field2) + 1 ] = 0;
must be ok... sure, you can optimize this ...
