When using CAPTION in SAS, what is the default behavior?

The default behavior of the CAPTION option in SAS is to ignore leading and trailing blanks. This is important because it allows for more consistent presentation of the text by ensuring that unnecessary spaces do not interfere with the layout or appearance of the output.

In practical scenarios, when a CAPTION is specified, any extra spaces before or after the actual caption text are trimmed away. This makes the output cleaner and avoids any unintended white space that can disrupt the formatting.

The other options do not align with the default behavior of the CAPTION in SAS. While one might think that keeping all formatting intact could be relevant, CAPTION is specifically designed to create a focused output by excluding irrelevant whitespace. Thus, the most accurate representation of how CAPTION works by default is indeed the behavior of ignoring leading and trailing blanks.
