MVS data set and file naming z/OS Communications Server: IP User's Guide and Commands SC27-3662-00 |

FTP subcommands can require a data set or file name. The format used to name a data set depends on the host system. Some systems limit the length of a data set name, and some systems are case sensitive. For information about the //DD file name syntax for FTP, see ddname support with FTP. Data set names in MVS™ consist of one or more names, called qualifiers, each from one to eight characters long, that are delimited from one another by periods. The leftmost qualifier in the data set name is the high-level qualifier. The rightmost qualifier in the data set name is the low-level qualifier. Partitioned data sets can be further qualified with a member name in the rightmost position. Qualifiers lying between them are called intermediate-level qualifiers. For example, in the data set name dog.bulldog.winston, dog is the high-level qualifier, bulldog is the intermediate-level qualifier, and winston is the low-level qualifier. Specify TSO sequential data sets in the following format: .----------------. V | >>-+------------+----+------------+-+--llev_qual--------------->< '-hlev_qual.-' '-llev_qual.-' Specify TSO partitioned data sets in the following format: >>-+-membername---------------------------------------+-------->< | .----------------. | | V | | '-+------------+----+------------+-+--(membername)-' '-hlev_qual.-' '-llev_qual.-'
