Oracle SQL*Plus Pocket Reference
Corrections
Page 3, the syntax for the sqlplus command
At the very bottom of the page, the definition of the HEAD option for
the MARKUP command-line parameter is incorrect. The text that you supply
for the head option is not written as <head text>. It is
written as <head>text</head>.
Page 74, the SET MARKUP command
The book states that SET MARKUP HEAD text causes text to
end up in the HEAD tag as <head text>. That's not quite correct.
The text that you supply to the HEAD option ends up in the document as
<head>text</head>.
