Coding ETO descriptors
IMS uses ETO descriptors to dynamically build terminal structures and user structures.
The four types of ETO descriptors are:
- Logon
- User
- MFS device
- MSC
The basic format for all ETO descriptors is:
- Column
- Description
- 1
- One of the following descriptor types:
L
- Logon descriptor
U
- User descriptor
D
- MFS device descriptor
M
- MSC descriptor
- *
- Comment line (ignored by IMS)
- 3-10
- Name of the descriptor, using the following conventions:
- Must be one to eight alphanumeric characters.
- For logon and user descriptors, characters are limited to A-Z, #, $, and @.
- For MSC descriptors, use the link name.
- 12-72
- One or more keywords and their parameters, separated by blanks. Use commas to separate multiple parameters for a single keyword.
- 73-80
- Optional sequence numbers (ignored by IMS).
