SYMPTOMS

Set a watchpoint on a string in a FORTRAN program by using the following line: 
   fred.eq.'test'
CodeView always returns the message "Operand types invalid for this operation."

CAUSE

CodeView does not support logical operations on Fortran strings (however, it does with C strings). Therefore, you cannot use the logical operator "eq" on the string for setting up the watchpoint.
