[Coin-ipopt] question:meaning of outputs, C_WATCH (wacthdog characters)

[saeed serpooshan]

hello
i have a question about IPOPT output ALFA(X), 
as you see here:
 
ITER     ERR       MU      ||C||    ||D||   ALFA(X) #LS  ...      
    0 .100D+01d .100D+00 .141D+01 .000D+00 .000D+00   0 
    1 .201D+01d .100D+00 .671D-15 .169D+02 .100D+01H  1 
    2 .920D-02d .100D+00 .312D-05 .347D-01 .100D+01f  1 
    3 .399D-02p .200D-01 .537D-02 .133D+01 .100D+01f  1 
    4 .951D-03d .283D-02 .149D-04 .815D-01 .100D+01h  1 
    5 .149D-03d .150D-03 .257D-05 .262D-01 .100D+01h  1 
   ........
 
each value of ALFA(X) is followed by 
a char 'H' or 'f' or 'h' such as
.100D+01H  or .100D+01f  or  .100D+01h
i read IPOPT.ReadMe file but i can't find what this means!
i see in it must be C_WATCH variable that is 
some info about watchdog but i can't find more info 
about meaning of each character.
can you help me?

thanks alot
