Library Code / subcode

Display only. CA-PanAPT displays the Library Code / subcode you have selected for viewing or maintenance.

Model Base

Required. Length: 1‑4. Type: alphanumeric, no embedded spaces.

This field serves two purposes:

• During modeling, the models create JCL and control statements members on the APTMDLO PDS. The models need to generate unique member names so that there are no conflicts between Library Codes, concurrent movement within the same Library Code at different levels (that is, test to QA at the same time as QA to production), and moves verses backouts.

The modeling facility assists the models by presenting them with a prefix that can be used to assure unique names. The prefix begins with a one character indicator as to whether a move or back out is taking place, a two character number indicating the relative position of the target library level, and the four character model base (with fill padding if it is less than four characters). This gives the models a unique seven character prefix.

To ensure a unique prefix, the model base for each Library Code must be unique. CA‑PanAPT ensures this while you are on this panel, and it does not allow you to continue if the model base is not unique.

• Sometimes you might need to control the order in which your Library Codes are presented to the modeling facility. If your models for your Source member Library Codes perform compiles, it might be necessary for you to process Copy/Include member Library Codes before Source member Library Codes. The Model base is used as a sort key for the modeling facility. If the model base of your Copy/Include Library Code is lower than that for your Source Library Code, then Copy/Include members are presented to the modeling facility first.

Note that this description is only an example. There are other ways to ensure that your compiles do not take place before your source is moved regardless of the model base.

The default for your Model Base is your four character Library Code name.

Edit Model Specifications or Browse Model Specifications

Required. Length: 1. Valid values: Y (Yes) or N (No).

This field is titled Edit Model Specifications when the action is ADD or CHG, and is titled Browse Model Specifications when the action is INQ or DEL.

Y

Edit or Browse the model specifications.

N

Bypass the specifications.

When you enter Y, the model specifications are staged out to a temporary PDS, so edit or Browse them. You are then taken into ISPF Edit or Browse on the PDS. There you find one member for each type of modeling specification. Any changes made while you are editing this PDS are copied into the Library Code when you are done. When you edit the members, keep in mind that each member is limited to 12 model specification lines. The ISPF editor does not stop you from adding more lines, but if you do so, CA‑PanAPT forces you to correct it once you return out of edit.

To end the Edit or Browse of the model specifications, enter the END command (PF3) from the member selection list. The Library Code Maintenance Model Specification panel redisplays, with the Edit/Browse Model Specifications field changed to an N.
