Local Arrays
Local arrays can be declared in a couple of different ways (Figure 22-5).
The sequence
0
:FLOAT
x[10]
creates an empty local
FLOAT
array of size 10. The
0
thatÕs on the stack
when this happens serves no purpose other than to be consumed by the dec-
laration. It just has to be there, thatÕs all.
The string
"This is a test"
declares an unnamed
CHAR
array. When declaring a string within a function,
the delimiters must be double quotes.
Unnamed numeric arrays can also be declared, as illustrated by
:INT
{1 2 3 4 5}
This type of declaration creates an array that is full (size = ready = 5).
The sequence
:CHAR
{10 13 32}
:PTR
whiteSpace
illustrates a method of ÒnamingÓ an unnamed local array. In this case, a 3 el-
ement
CHAR
array is created by the first declaration, and itÕs address is put
:FCT
MyTest
{
0
:FLOAT
x[10]
"This is a Test"
:INT
{1 2 3 4 5}
:CHAR
{10 13 32}
:PTR
whiteSpace
}
Figure 22-5. Four examples of declaring local arrays.
FLOAT
array named x. Size
is 10, Ready is 0.
Unnamed
CHAR
array.
Unnamed
INT
array.
Unnamed
CHAR
array, with a local
pointer to refer to it.
