EQUEL accepts the BASIC record type in variable declarations, providing the record has already been declared to EQUEL.
The following data types are illegal and will cause declaration errors:
     gfloat
     hfloat
Neither the preprocessor nor the runtime support routines support gfloat or hfloat floating-point arithmetic. You should not compile the BASIC source code with the command line qualifiers gfloat or hfloat if you intend to pass those floating-point values to or from Ingres objects.
