DEFM Define Memory
This directive stores a string as data. There are two formats for the instruction:
DEFM n,<Ascii character string>
where n is a decimal number that indicates the number of characters required in the string. A comma must follow the number and the character string is placed immediately after the comma. (A comma can still be used in the character string).
When n is greater than the number of characters in the character string, then $20's (Ascii space character) are appended to the data generated to make up the total number bytes.
When n is smaller than the number of characters in the character string, then the string is truncated with only the first n characters being used.
This form of fcc requires the character string to be enclosed in delimiters (symbolised above by 'd'). The delimiter may be any valid character including a digit (but if a digit is used, the first character of the string should not be a comma since the cross-assembler will then assume that the operand is the previous form of fcc). The same delimiter must be used to end the string as is used at the beginning.
