You should not need to escape that statement at all.  SNL allows normal C function calls as part of its syntax.  I think you can remove the %% in that line.

But is the problem there that your statement is not inside a when() block?

Subject: SNL with C

Hi,
I a newcomer to SNL.

I have a library to which I link my snl.  In a global entrance block, I can successfully call
one of the functions.  Later I added the use of another function in a state set and now
I can no longer compile.

ss SS1 {

  state Offline {
    /* Get PV relevent PV information */
    when (SS1mon == 1) {
      SS1state = 1;
      pvPut(SS1state);
    } state Pumping
  }

  state Pumping {
    /* Get PV relevent PV information */
    %%if (StateReadCDB()) printf("SS1-Pumping: success\");
    when (SS1vac <= 1.0e-4) {
      SS1state = 2;
      pvPut(SS1state);
    } state Pumped_Warm
  }
... continued
}


The error at compilation/linking is: 
converting ../sncMICEStates.stt 
/home/epics/epics/Support/seq/bin/linux-x86/snc +r   ../sncMICEStates.stt -o sncMICEStates.c.tmp
syntax error: line no. 96 (../sncMICEStates.stt)
     state option list
make[3]: *** [sncMICEStates.c] Error 1
make[3]: Leaving directory `/home/epics/epics/iocTops/MICEStates/MICEStatesApp/src/O.linux-x86'
make[2]: *** [install.linux-x86] Error 2
make[2]: Leaving directory `/home/epics/epics/iocTops/MICEStates/MICEStatesApp/src'
make[1]: *** [src.install] Error 2
make[1]: Leaving directory `/home/epics/epics/iocTops/MICEStates/MICEStatesApp'
make: *** [MICEStatesApp.install] Error 2

where line no. 96 is the escaped call to the library function in my Pumping state.  The error "state option list"
doesn't tell me anything.

Help please,
Pierrick
