Appletips
Article Abstract:
Two programs are presented. Both programs are written in Assembler. The first is a subroutine that will not only print the DOS error message from within an ONERR GOTO subroutine without incorporating its text in the main program but will also print any appropriate Applesoft error messages. The second program assigns comma a new value to skirt the problem of its acting as a delimiter when text is read back to disk. Also included is a simple method of accessing the assembler from the keyboard if you have a language card.

Appletips: Lower Case Printing Without Clumsy Coding
Article Abstract:
Most Apple computers will not display lower case characters; however, it can be done by making changes in the printer using the CTRL S command. By changing the DOS output to point to the $BA69 output address and using CTRL S to select and de-select inverse text; it is possible to move from upper case to lower case characters. The machine code and a sample program are shown.
