SYMPTOMS
When using a SEEK command in the FOR clause of the APPEND FROM command, the _TALLY system variable does not reflect the additional records added to a table.



CAUSE
The SEEK command is moving the record pointer in the table while the APPEND FROM command is adding records. This prevents the _TALLY from returning the proper count.



RESOLUTION
Place the SEEK command, or any other command that may move the record pointer, outside of the APPEND FROM command. Use a FOR...NEXT or an IF...ENDIF loop structure to process and limit the records.



MORE INFORMATION
The code example below creates two tables and populates them with one and three records, respectively. After creating an index on the second table, the APPEND FROM command adds records based on the results of the SEEK command. The SEEK command, however, moves the record pointer while records are being added, which causes _TALLY to return an incorrect value.

Steps to Reproduce Behavior
Create a program with the following code and run it: CREATE TABLE test1 (fld1 c(10)) CREATE TABLE test2 (fld1 c(10)) INSERT INTO test2 (fld1) VALUES ('AA') INSERT INTO test1 (fld1) VALUES ('AA') INSERT INTO test1 (fld1) VALUES ('AA') INSERT INTO test1 (fld1) VALUES ('BB') SELECT test2 INDEX ON fld1 TAG fld1 APPEND FROM test1 FOR NOT SEEK(fld1,'test2') ? _TALLY _TALLY returns zero (0) instead of 2.
