Q
The quad
quote
symbol
is
formed by overstriking
the
quote
symbol'
and the quad
symbol
O.
The quad quote operates the same way
as
the quad when requesting
input, except
that
the
data entered
is
treated
as
character data. For example:
CAN'T
x
CAN'T
Xf-r.:1
'CAN"
T'
X
'Cf-iN'
,
T'
Note: If a system command
is
entered for a quad
quote
input request, the system
command
is
treated as a character string and will
not
be executed.
See Chapter 6 for more information on quad quote input or
output
within a user-
defined function.
