Record terminator slash (/) in format not supported

NOTE: Calling sequence to IFSF_LINELIST has changed. If vacuum
wavelengths are required, or other wavelength units, or
to suppress this message, use ARGSLINELIST structure in
initialization procedure. Default is now air waves.

GDL output is not as expected:

GDL> print,'NOTE: Calling sequence to IFSF_LINELIST has changed. If vacuum',$
GDL> ' wavelengths are required, or other wavelength units, or ',$
GDL> ' to suppress this message, use ARGSLINELIST structure in ',$
GDL> ' initialization procedure. Default is now air waves.',$
GDL> format='(A0/A0/A0/A0)'
% PRINT: Infinite format loop detected.

Thanks for the report!
in other terms,
print,"a","b",format='(a/a)' is badly handled by the GDL interpreter.
The documentation says that '/' and ',' are both format separators, not only ','.
To be solved...
Note that format='(a/,a)' works and is a temporary solution.
