Hi,
   First I am sorry for my poor English and the mistakes would make.
   I am new to EPICS and I met some question when using asyn. Hoping your advices for my question.
   I used the asyn to control the motor( do it as the tutorial in asyn ), if I want to move the different step, I have to change the number and make it. I want to find an easy way.

Here is the my file( you can see these ):
-----------------------------------------------------------------------
/*
I have the devXXX.c,  devXXX.db,  devXXX.dbd  file,
here is some of my words in devXXX.c( key part ),
you could only see the four part.
*/
-------------------------------------------
#define EOSNL "\r\n"
static sturct gpibCmd goibCmds[]=
{
{&DSET_SO,GPIBCMD,IB_Q_HIGH,  "\x02RPS1/0/300/0"EOSNL,   NULL,0,200,NULL,0,0,NULL,NULL,EOSNL}  /* "\x02RPS1/0/300/0" is the command sent to motor, 300 is the distance */
}
------------------------------------------
over.

  I want to change the "300" with a pv in "\x02RPS1/0/300/0"EOSNL, then I could change the value at will, no need to make again and agian.
  When I try to add the pv, make would error, I don't know how to solve it.

Hope your answer.
Thank you in advanced.
