MORE INFORMATION

Steps to Reproduce Problem

  1. Load FoxPro.

  2. Copy the following code into a program: 

         CLEAR ALL
     CLEAR
     CREATE TABLE people (pID C(5), pNAME C(10), pCITY C(10))
     APPEND BLANK
     REPLACE pID WITH 'A1234'
     REPLACE pNAME WITH 'Mickey'
     REPLACE pCITY WITH 'Bellevue'
     INDEX ON pID TAG id
     INDEX ON pNAME TAG name


         ? KEYMATCH('A1234','PEOPLE')    && Invalid function argument...
     ? KEYMATCH('A1234','PEOPLE',1)  && .T.
     ? KEYMATCH('A1234','PEOPLE',2)  && .F.
     ? KEYMATCH('A1234','PEOPLE')    && .F. instead of "Invalid..."
     ? KEYMATCH('Mickey','PEOPLE',2) && .T.
     ? KEYMATCH('A1234','PEOPLE')    && .F. instead of "Invalid..."

  3. Run the program.

When the "Invalid function argument, type, or count" error message occurs on the first ? KEYMATCH('A1234','PEOPLE') command, choose the Ignore button.

Note that the second and third issuances of the same command return a .F. (FALSE) value instead of the "Invalid function argument, type, or count" error message.

If you put the KEYMATCH() commands in the following order 

     ? KEYMATCH('A1234','PEOPLE')    && Invalid function argument....
     ? KEYMATCH('A1234','PEOPLE',2)  && .F.
     ? KEYMATCH('A1234','PEOPLE',1)  && .T.
     ? KEYMATCH('A1234','PEOPLE')    && .T. instead of "Invalid..."
     ? KEYMATCH('Mickey','PEOPLE',2) && .T.
     ? KEYMATCH('A1234','PEOPLE')    && .F. instead of "Invalid..."
the first ? KEYMATCH('A1234','PEOPLE') command returns the "Invalid function argument, type, or count" error message, the second issuance of the same command returns .T. (TRUE), and the third issuance of the same command returns .F. (FALSE).
