That makes sense:
Char * fieldP;
Char * recordP;
Creates two character pointers.
Char * recordP, fieldP;
Creates one character pointer and one character.
This is one of my long standing objections to the practice of creating
'Ptr' data types (or LPxxx in Windoze hell). You have to know that the
'user type' equates to 'usertype *', or you can create syntactical
problems like the one above.

Believe me or not, the error goes away after I declared the variable in
a
separate line, e.g.
Char * fieldP;
Char * recordP;

Elizabeth,
fieldP is declared as a char. The way you have it now is that fieldP is
an
actual char
not a pointer (which is what MemHandleLock() returns).
Try:
Char * recordP, *fieldP;
