Program – Saved RPN Lists (Removal)

The translated RPN lists for program lines were being saved in the line information list, which also contains the offset of the line within the program code, the size of the line and the index to the error list if the line has an error.  These lists were originally used as the source of the data for the program view and were also used to detect when lines changed (by comparing the translated RPN list of the new line with the saved RPN list).

The use of the RPN lists for the program view was removed when the program code array was implemented.  With the decode routine, the program code of the lines can now be converted to an RPN list.  The line change detection in the update line routine was modified to decode the code of the line for the new line being changed to an RPN list, which is compared to the translated RPN list of the new line.  With the RPN lists in the line information list no longer being used, this variable was removed along with all references to it.

A problem was found when RPN lists were compared.  The strings of tokens other than REM commands, REM operators and string constants (whose strings comparison must be case sensitive) should use a case insensitive string comparison.  However, the case sensitivity argument was not supplied to the compare call, so the default comparison used was case sensitive.  The correct argument was added.
