The literal-text string operator (< >) informs the assembler that the enclosed text should be treated as a single string rather than separate arguments. The syntax is
< text >
The text is treated as a single argument even if it contains parameter separators. Some typical parameter separators are commas, spaces, tabs, etc. The assembler removes the angle brackets and uses text as the argument.
When we invoke this macro as
range_error1 1, < Assignment mark >, < 0 to 25 >the macro expansion will look like this
err_msg1 DB "Assignment mark: out of range", 0 range_msg1 DB "Correct range is 0 to 25", 0
This operator can also be used to force the assembler to treat a character
literally by removing its default special meaning.
For example, <;> passes ; as an argument without treating it
as the comment operator. This can also be done using
the literal-character operator, as will be seen next.
