typedef struct StrListType {
char prefixString; // we assume it's empty
char numStringsHiByte; // we assume it's 0
char numStrings; // low byte of the count
char firstString[1]; // more than 1-all concated together
} *StrListPtr;
... The easiest way to crate such an array is with
SysFormPointerArrayToStrings. This [system] routine takes a concatenation
of null-terminated strings and returns a newly allocated array that points
to the beginning of each string in the concatenation. ...
