an intranet.
-
user catalog
- In Mainframe Express, an alternative catalog for defining the
mainframe data sets used by a project. Up to 32 user catalogs can be
used by a project in addition to the system catalog. Each user catalog
is associated with a user node.
-
user id
- An eight-character identifier associated with a CICS user. Users must
supply this identifier, together with a password when they sign on at a
terminal. The user id is specified in the SNT entry for the user.
-
user node
- The high-level qualifier of the data sets that are defined in the
associated user catalog. Mainframe Express searches for data sets with
this qualifier in the user catalog first, and then the system catalog.

the record length is stored with each record, which is then transferred
to the PC and used to recreate the original file.
-
VCRECGEN2
- A Mainframe Express utility that runs on the mainframe. It reads an
uploaded PC file in which the record length is stored with each record
and writes a mainframe file with variable length records.

Virtual Sequential Access Method
- An access method for direct or sequential processing of fixed and
variable length records on direct access storage devices. The records in
a VSAM data set or file can be organized in logical sequenc e by a key
