Parameters

table-name: Specifies the name of the table to be opened.
WRITE: Specifies that the table is being accessed for update. The updated table can subsequently be saved on disk by use of the TBSAVE or TBCLOSE service. This option is the default.
The WRITE/NOWRITE usage of a shared table must be consistent on all TBOPEN and TBCREATE requests. That is, all requests for a given shared table that result in concurrent use of that table must specify the same WRITE or NOWRITE attribute.
NOWRITE: Specifies read-only access. Upon completion of processing, the virtual storage copy should be deleted by invoking the TBEND or TBCLOSE service.
library: Specifies the name of a DD statement or LIBDEF lib-type that defines the input library. If specified, a generic (non-ISPF) ddname must be used. If this parameter is omitted, the default is ISPTLIB.
SHARE: Specifies that the table in virtual storage can be shared between logical screens while the user is in split-screen mode. The TBOPEN request from the first logical screen reads the table into virtual storage and opens it. Subsequent TBOPEN requests from other logical screens use the same table (and same CRP) that is in virtual storage.
A successful TBOPEN or TBCREATE request causes the use count in the table to be incremented by one. The use count determines the action taken by subsequent TBEND and TBCLOSE requests.
buf-len: Specifies a fullword fixed binary integer containing the length of "buffer".
buffer: Specifies a buffer containing the name of the service and its parameters in the same form as they would appear in an ISPEXEC call for a command procedure.
