They are similar with these two exceptions:

(1) When there is a string on level 1 containing the name of a CAS command (e.g. "DEF"), CASCMD jumps to that entry in the CAS command catalog, whereas HELP always starts at the top of the CAS command catalog.

(2) CASCMD always drops the contents of level 1 from the stack, whereas HELP leaves it on the stack.

Both CASCMD and HELP push something onto the stack when they exit, namely a zero when ON or EXIT are pressed, or the displayed example when ECHO is pressed.
