FINCSTP           Increment Stack Pointer     Exception Flags: None

FINCSTP

       Logic:      TOP . TOP + 1

     FINCSTP increments the stack top pointer in the status word. It is not
     equivalent to popping a register from the stack. This instruction does
     not change any tags or the contents of any registers.

     FDECSTP is the accompanying decrement instruction.
