Declare 1 constant. This can be done just below the prototype section. Put the following divider above the constant section.
;************************ Constants ***************************
Declare a constant LF to hold the ASCII value for a linefeed: 0Ah
A linefeed moves the cursor to the next line.
You can embed a LF in your declaration of the string variables below.
Example: name byte "Fred Kennedy",LF,0
If the above string were printed with WriteString as follows, Fred Kennedy would print then the cursor would move to the beginning of the next line.
movedx, offset name
callWriteString
You could also embed a LF at the beginning of a string which would move the cursor to the next line then the string would print:
name byte LF,"Fred Kennedy",0
See WriteStringLFconstants.asm on the class web site for examples of declaring strings with embedded LF and how to declare constants.
