Info

SERIAL SERIAL Syntax SERIAL; is not a full logic command. It is an command option that can be specified with a DETERMINE; or LOOK.UP; command only, to increase the efficiency of Profile accesses in Copy.From Ispecs. The SERIAL; command option retains the pointers to the Profile when it is first accessed and, on subsequent accesses, simply retrieves the next record without reading through the Profile again. The SERIAL; command option is valid only in Copy.From Ispecs. When GLB.COPY is equal to 1, the DETERMINE; command will start retrieving records at the point specified in the DETERMINE; command, until End-of-file is detected or until a BREAK; is executed. When GLB.COPY is greater than 1, the DETERMINE; command will continue retrieving records from the last record previously retrieved, and not from the point specified in the DETERMINE; command. Caution Using the SERIAL; command option at other parts of the Copy.From cycle, having not used it on the first copy, will produce unpredictable results. The results will differ from host type to host type, and could cause problems when porting <strong>LINC</strong> Systems between different hosts. When a DETERMINE; command with the SERIAL; command option reaches end-of-file, the buffer containing the dataset records continues to contain the data values of the last record read. Any subsequent reads using the DETERMINE; command with the SERIAL; command option will not alter those values. Since the success of the use of the SERIAL; command option depends upon the setting of the pointer, the same Profile should not be accessed elsewhere in the same logic, or unpredictable results can occur. Also, the SERIAL; command option must be executed in the first cycle of the logic (when the System Data item GLB.COPY has a value of 1). See the ‘‘Example’’. The SERIAL; command option is associated with a loop-forming variant of the DETERMINE; or LOOK.UP; command, and should only be used in Copy.From Ispecs. It must appear on the same logic line as the associated DETERMINE; or LOOK.UP; command. The SERIAL; command option is ignored in an Ispec that is not a Copy.From Ispec.

Example <strong>Reference</strong> SERIAL An Event DRINQ has a Copy.From line number of 4 and a MAX.COPIES value of 5. The data item STARTCUST is used to enter the starting customer. The Data items CUSTOMER (which has LINK; IF.PRESENT applied to it) and BALANCE are part of the Copy.From area of the screen. Part of the logic for DRINQ is as follows: Suppose CUST has records with CUSTOMER values: ARNOLD, BRUCE, COLLEEN, DIANE, EDWARD,andFRED. If STARTCUST has the value BARRY when the loop is entered the first time, the LOOK.UP; FROM command finds BRUCE. The second time (when GLB.COPY is 2), the LOOK.UP; FROM command will find COLLEEN, and not reread BRUCE. The third time (when GLB.COPY is 3) the LOOK.UP; FROM will find DIANE, and not reread BRUCE and COLLEEN. ‘‘LOOK.UP; (LU;) Commands’’ and ‘‘DETERMINE; (DT) Commands’’. v 1-225
