Translator – Assignments (Release)

The test code was modified to output “<ref>” after tokens that have the reference flag set. For the third set of test inputs used for testing arrays and function, there are some differences because the reference flag is now set for array subscripts and function arguments. The unexpected comma error was also changed (replaced with separate unexpected comma errors). For the assignment statement test inputs (fifth set), a lot of different statements were needed to test the many situations that can occur. Many have already been discussed. As bugs were discovered, new test statements were added. There are 9 new possible assignment related errors, so there are statements for each of these.

Some more comma related bugs were discovered, including assigning an multiple dimension array element as in the statement “A(B,C)=D” added an assign list operator instead of an assign operator; and the statement “A(B+C,D=E)=F” generated an error. The bottom line was that the counter stack not empty check also needed to be added to the comma operator code. This resulted in new error “unexpected comma in parentheses” being added.

I'm changing the way the changes made to the code are dated. Previously, all the dates were changed to the date of the release – like all these changes were made the same day, which may not have been the case. The changes are becoming rather involved over many days and this method is not efficient. From this release on, the date will be when the changes are actually made. The time stamp of the file may be more recent because of going back and editing the change history at the top of the file.

I have also decided to put this project under software version control, specifically CVS – with the next release. I have working knowledge of CVS and I discovered that either MSYS came with it, or I installed an MSYS/CVS package. The current version numbers in the source files will be removed and replaced with the CVS revision ID tag. These versions were my attempt at version control anyway. Maintaining all the difference versions as zip files and directories is also not efficient.

The code now handles assignment statements and ibcp_0.1.8-src.zip has been uploaded at Sourceforge IBCP Project along with the binary for the program. The release notes now contain a Planned Roadmap to show upcoming development. Next the handling of data types...
