Presetting Automatic Naming Identifiers

Two-character automatic naming identifier that is incremented each time a new name is assigned, ranges from AA to T9 for file names and from AA to Z9 for other objects. This limits the product to 684 file names and 936 names for each of the other object types.

To avoid the inconvenience of reaching these limits you can preassign the next unique code to be used by the automatic naming algorithm for each object type using the Edit Next Mnemonic (YEDTNXTMNC) command. This command displays the following interactive panel.

Note: You need to be out of your model when you run YEDTNXTMNC and you need *DSNR authority to edit the panel. If multiple models use the same naming library, ensure that no one is using any of the models.

This panel is divided into two parts as follows:

Change Next Object Prefix for Member Names—The top section of the panel applies to physical and logical files (FIL) and functions (MSG). The mnemonic for these objects is the system prefix; namely, the OBJPFX model value. This table describes the panel options:

Option		Description
ID Mnemonic	FIL	Last 2-character identifier used for a file name. Use this to determine how close you are to the limit (T9)
	MSG	Last 2-character identifier used for a program name. Use this to determine how close you are to the limit (Z9)
Current Prefix		The current OBJPFX model value.
Next Prefix		The mnemonic to use when the naming algorithm runs out of names. When the name limit is reached for either files or programs, the OBJPFX model value is updated to this value.

Assign the next mnemonic to be used when the automatic naming algorithm runs out of names by typing a two-character mnemonic for the ‘Next Prefix’ option and press Enter.

When the name limit is reached for either files or programs, the ‘ID Mnemonic’ is reset to AA for both FIL and MSG objects and the value you entered becomes the new mnemonic when assigning file and program names. The OBJPFX model value is also updated to this value.

Change Next Field Type Mnemonic—The bottom section of the panel applies to field types. This table describes the panel options:

Option	Description
Field Type	Three-character field type code.
Identifying Mnemonic	Last 2-character identifier used when assigning a field name for the corresponding field type. Use this to determine how close you are to the limit of Z9.
Type Code	The current Type mnemonic used for the corresponding field type.
Next Code	The Type mnemonic to use when the naming algorithm runs out of names for the corresponding field type.

Assign the next mnemonic to be used when the automatic naming algorithm runs out of names for a field type by typing a two-character mnemonic for the ‘Next Code’ option and press Enter.

When the name limit is reached for the field type, the ‘Identifying Mnemonic’ is reset to AA and the value you entered becomes the new mnemonic when assigning field names for this field type.

Note:

Use the F20 function key on the YEDTNXTMNC panel with care. Like the Enter key, it updates the YALCVNMRFP file but without performing error checking. It is intended for use only in unusual circumstances; for example, if you need to use the same mnemonic for two different field types.
Since format names are combined with the associated file name identifier, the two-character identifier for formats is simply reset to AA when the name limit is reached.
