Dear Colleagues,

  We, KEKB accelerator control group,  are developing a tool to support development of GP-IB device support 
 routines.  It consists of file format define GP-IB device ( GP-IB device 
 description language, gdl) and translater(gdc) which translate this file 
 into c source code used as GP-IB device support routines.  It also 
 generate command list in the gdl file. Please find the simplified descrption
 of gdl file format, a sample input  and a sample of command list
 generated by gdc at the end of this mail.
 
  The first version of gdl/gdc is under test in KEK. gdl/gdc is designed 
 and implemented by Mr. Susumu Yoshida of KANTO information service.
  
  your comment or suggestion will be appricated.
  
  Regards,
