Common Parameter Values
Parameter values might be names (strings) or numbers.To use spaces as part of a name 
parameter, enclose the name value in double quotes. For example, the expression 
“System Name with Spaces” forces the system to accept the spaces. Empty strings (““) 
are not valid user-defined strings. Table 2 describes common parameter values and 
value formatting.

following formats:
a
