1.The LMOPEN service opens the data set associated with a given data ID so the data set can be either read from, using LMGET, or written to, using LMPUT.
2.The LMINIT service must be completed before LMOPEN can be used.
3.For each LMOPEN invocation, you should invoke a matching LMCLOSE service.
4.The data ID associated with the data set to be opened. The data ID has been generated by the LMINIT service. The maximum length of this parameter is 8 characters.
5.Whether the data set is to be opened for reading or writing. INPUT is the default.
6.INPUT specifies that the dialog invoking the service uses the LMMFIND and LMGET services to read from the data set.
The enqueue value for the LMINIT service can be SHR, EXCLU, or SHRW.
7.OUTPUT specifies that the dialog invoking the service uses LMPUT and either LMMADD or LMMREP to write to the data set, or
uses LMMDEL or LMMREN to change the data set. The enqueue value for the LMINIT service can be EXCLU, SHRW, or MOD
