FCN - Form
constant character string terminated with a null byte
[label] FCN string
The FCN directive is used to store null terminated ASCII strings into
consecutive bytes of memory. The byte storage begins at the current program
counter. If a label is present it will be assigned address of the first byte in
the string. Any of the printable ASCII characters can be contained in the
string. The string is specified between two identical delimiters which can be
any printable ASCII character. The first non-blank character after the FCN
directive is used as the delimiter. The assembler will automatically append a
null byte ($00) to the end of the string.
Example:
fcn "some string here" fcn /some string here/
Additionally CASM supports the ability to include trailing
byte declarations similar to FCB statements to the end of the FCN declaration.
