FIX: "Index Internal Consistency Error" Occurs with IDX Index

   INDEX ON <fieldname> TO <filename> COMPACT
					

MORE INFORMATION

The problem occurs after an IDX index is created and used with the table. When the user browses the table and changes the data in the indexed field, moving up or down in the Browse window several times with the arrow keys, the scroll bar, or the Page Up and Page Down keys produces the error.

Steps to Reproduce Behavior

1. Run the following code from a .prg file or the Command window in Visual FoxPro:

   INDEX ON <fieldname> TO <filename> COMPACT
         USE HOME()+"samples\data\customer"
         COPY TO HOME()+"Test.dbf"
         SET MULTILOCKS ON
         USE test
         INDEX ON cust_id TO junk   &&  COMPACT
         =CURSORSETPROP("Buffering", 5)
         BROWSE

2. When the Browse window appears, change the data in the cust_id field. Press the Down arrow key and move through the records to the end of the table. If necessary, press the Up arrow key and move through the records to the beginning of the table. The error should appear. Sometimes moving through the data with the Page Up and Page Down keys also causes the error.
3. Remove the "&&"s from in front of the COMPACT clause in the code above and rerun the code to rebuild the index. The error does not occur when you scroll up and down in the Browse window after changing data in the index key field.
