I have implemented the SUBSTITUTE function for formula cells. I have also filled in the SUBSTITUTE "FORMULA" and "EXPECTED VALUE" rows of the file src/scratchpad/testcases/org/apache/poi/hssf/data/FormulaEvalTestData.xls with 17 test cases. All tests pass.
Created attachment 21285 [details] Generated using svn diff > FormulaSubstituteFunction.patch This is a patch file, generated by running: svn diff > FormulaSubstituteFunction.patch After I finished implementing the SUBSTITUTE function.
Created attachment 21286 [details] Contains the files I modified to implement and test the SUBSTITUTE function. This tar file contains two files that I modified to implement and test the SUBSTITUTE formula function. The first file is: src/scratchpad/src/org/apache/poi/hssf/record/formula/functions/Substitute.java This is where the SUBSTITUTE 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 1296 and 1297), the "FORMULA" and "EXPECTED VALUE" rows for the SUBSTITUTE function. This row contains the test cases for SUBSTITUTE. These tests run successfully and are run automatically when the ant task "test" is executed.
Thanks, applied
