LAP<br />The LAP data class is the defintions for each Logical Application (a grouping of function codes). The index listing for the FCD data class above also shows Logical Applications.<br />## <br />ELT<br />The ELT data class is the definitions for data elements. A data element is a record or portion of a record, it is the (cont.)<br />basic unit of transfer between the database (files) and programs. The ELT definition provides for security (cont.)<br />authorization requirements to control who may develop batch and online applications accessing the data element. The ELT (cont.)<br />data class is subordinate to the DCL (Data Class) definition. A batch report documenting all available parameters and (cont.)<br />information, including where-used, can be produced using the DCLDOC utility program with a control card (cont.)<br />of:<br />DCLDOC xxx<br />where xxx is a valid DCL name.<br /># <br />Appendix C -- Global Changes<br />## <br />Security Entities<br />The security entities in MAGEC can be maintained using the standard ...ADD, ...CHG, etc. functions as shown in this (cont.)<br />tutorial; or they can often be maintained using several handy global change functions provided.<br />A global change function simply allows you to select a set of records meeting a particular set of criteria and to (cont.)<br />update them all in one transaction. The special function codes used to do global changes to security entities (cont.)<br />are:<br />SIFGBL operator profiles<br />&nbsp;<br />FCDGBL function codes<br />&nbsp;<br />DVCGBL video and printer devices<br />&nbsp;<br />These functions all operate in generally the same way. You first enter the function code (with a blank key value, (cont.)<br />usually), then you receive a screen asking you to indicate the changes you wish to make. For example, in the FCDGBL (cont.)<br />process you will be presented a screen which resembles the FCDCHG screen, but has underscores in all the data fields. (cont.)<br />You can enter the desired value into the field (or fields) you wish to alter, leaving all other fields untouched. For (cont.)<br />example, if you wished to change the Logical Application for a set of function codes to '01', you would type '01' into (cont.)<br />the Logical Application field and not type anything into any other screen field.<br />Next, you will be taken to a sequence of screens designed to let you select which function codes are to be updated. The (cont.)<br />selection is done using a screen which is very similar to a standard ...SCN function, wherein you enter a selection (cont.)<br />mask to search for matches. For example, you might enter 'VAC' into the first three positions of the "function code" in (cont.)<br />the dot mask line.<br />Once the screen is returned to you displaying the function codes which match your selection mask, you have one more (cont.)<br />chance to de-select any function codes you do not wish to update. This is done by pointing with the cursor and pressing (cont.)<br />a PF key; instructions are displayed on the screen to help you remember which key to use.<br />When you are satisfied that you have selected the function codes you wish to update, you simply press a PF key to tell (cont.)<br />MAGEC to apply the changes. If there were more items than could be displayed on one screenful from the scan, you can (cont.)<br />press a PF key to proceed forward to process another screenful in exactly the same way.<br />Online instructions are presented at the bottom of every panel in this sequence. No updating is done until you press (cont.)<br />the appropriate PF key at the end of the sequence to indicate that you wish to apply the updates to the "marked" items. (cont.)<br />You can abort the sequence harmlessly at any time.
