The LIST option specifies list-directed output.
The PUT LIST statement causes each value specified by the output list to be written to the stream file without the use of a format item. Each value to be output is converted to a character-string value using the normal rules for converting to a character string given in the chapter Data Type Conversions.
If the original output value is a bit string, the resulting character string is enclosed in quotation marks and a B is appended to its right end.
