I have implemented the MID function for formula cells. I have also filled in the MID "FORMULA" and "EXPECTED VALUE" rows of the file src/scratchpad/testcases/org/apache/poi/hssf/data/FormulaEvalTestData.xls with 17 test cases. All tests run and pass.
Created attachment 21281 [details] Generated using svn diff > FormulaMidFunction.patch This is a patch file, generated by running: svn diff > FormulaMidFunction.patch After I finished implementing the MID function.
Created attachment 21282 [details] Contains the files I modified to implement and test the MID function. This tar file contains two files that I modified to implement and test the MID formula function. The first file is: src/scratchpad/src/org/apache/poi/hssf/record/formula/functions/Mid.java This is where the MID function is implemented. The second file is: src/scratchpad/testcases/org/apache/poi/hssf/data/FormulaEvalTestData.xls I modified two rows in this file (rows 884 and 885), the "FORMULA" and "EXPECTED VALUE" rows for the mid function. This row contains the test cases for mid. These tests run successfully and are run automatically when the ant task "test" is executed.
Thanks, applied
