Some A-Shell functions are implemented as both as subroutines and print tab statements. The syntax may be slightly different and they may be used in different contexts, but the functions of these pairs are approximately the same. Refer to the _See Also_ heading in the current topic to see the corresponding statement, and read the documentation on both statements to determine which is appropriate for your needs and context. Refer to [Subroutine Wrappers for Print Tab Statements](subroutine-wrappers.md) for a more complete discussion.
