LOOK.UP; (LU;) Commands Single record LOOK.UP; commands in Performable Global Logics behave differently depending on whether they are inserted in a Report or inserted in an Ispec., where that Global Logic attempts to look up a non-existent key. The command sets GLB.STATUS to *****, and processing continues from after the LOOK.UP; command. The contents of GLB.STATUS should always be checked after a LOOK.UP; command in a Report or, if a loop is created, after the END; or END.EXIT; command of that loop. The value of GLB.STATUS resulting from the LOOK.UP; command can be directed to another data item by using the GLB.STATUS; command. This is especially useful where many commands can update GLB.STATUS, or if you want to test the success of a single LOOK.UP; command. In LDA In Ispecs, if a single LOOK.UP; command fails to find a record and the GS; command is not included, an error message appears. If the GS; command is included, the error is suppressed and the data item referenced by the GS; command is set to *****. For other LOOK.UP; command variants, if no record is found, GLB.STATUS is set to *****. If the first attempt is successful, GLB.STATUS will not be set in the event of a subsequent failure to retrieve a record. It is not set at End-Of-File, for example. Always check the contents of GLB.STATUS after a LOOK.UP; command or, if a loop is created, after the END; or END.EXIT; command of that loop. The new value of GLB.STATUS, resulting from the LOOK.UP; command, can be directed to another data item by the GS; command. This is especially useful where many commands may set GLB.STATUS. In Reports, GLB.STATUS is set to ***** for all variants of the LOOK.UP; command, including the single version. Logically Deleted Records In Ispec logic, logically deleted records are read into memory by a LOOK.UP; command, but they are effectively ignored; that is, they are not returned for use by your LINC logic. If, however, the last record read by a LOOK.UP; command is logically deleted, it will remain in memory after the command . You should test for this situation. See the following example. The setting of GLB.STATUS also depends on whether records, although physically present, are marked as logically deleted. If every record retrieved by a LOOK.UP; FROM or LOOK.UP; EVERY is a logically deleted record, then GLB.STATUS will be set to *****. In Report logic, logically deleted records are brought into memory by LOOK.UP; commands. You must include specific logic if you want to exclude logically deleted records. 1-154 v
LOOK.UP; Commands for UNIX ORACLE LINC Systems References LOOK.UP; (LU;) Commands For UNIX LINC Systems, on occasion ORACLE may select the wrong index (Profile), where the Indexes have identical keys but in a different order. This can have performance implications for your UNIX LINC System. This issue and suggested solutions are described in your UNIX LINC Administration and Operations Guide. ‘‘SECURE’’. ‘‘SERIAL’’. ‘‘MULTI’’ (2200 Series target hosts only). ‘‘GLB.STATUS’’. ‘‘GLB.STATUS (GS)’’. ‘‘DETERMINE; (DT) Commands’’. v 1-155
