Attribute for <SPACER ...>
SIZE = integer

SIZE gives the horizontal size for the space when you use HORIZONTAL, and vertical size when you use VERTICAL. Why didn't they just use the WIDTH and HEIGHT attributes? Apparently that would have just made too much sense.

this code	produces this
There was a long <SPACER TYPE=HORIZONTAL SIZE=50> pause<BR> and then he <SPACER TYPE=HORIZONTAL SIZE=100> spoke.	There was a long pause and then he spoke.
hi there! <SPACER TYPE=VERTICAL SIZE=50> hi there! <SPACER TYPE=VERTICAL SIZE=200> hi there!	hi there! hi there! hi there!
