MAT ASSIGNMENT (SCALAR VALUE)
This statement allows you
to
assign a specified scalar value
to
each element
of
an
array. The syntax
of
this statement
is
as
shown:
MAT
array-name [(rows [,columns)
))
= (scalar-exp)
where:
array-name
is
the
name
of
the
arr,ay
that
receives the values.
rows, columns are the redimension specifications
of
the
array (see Redimensioning
Arrays).
scalar-exp
is
the
value
to
be assigned.
When this statement
is
executed,
the
parenthesized scalar expression
is
evaluated
and each element
in
the
named array
is
set
to
that
value.
If
redimension specifications are included,
the
truncated integer portion
of
each
expression
in
rows, columns
is
used
to
redimension
the
array before
the
scalar value
is
evaluated and assigned
to
each
of
the
array elements.
For character arrays, if the expression
is
less
than 18 characters, it
is
padded on
the
right with blanks
to
a length
of
18 before being assigned.
If
there are more than 18
characters
in
the
expression, only
the
leftmost 18 characters are assigned
to
the
array elements.
Notes
About
MAT
(Scalar)
• The scalar expression
to
the right
of
the equal sign must be
of
the
same type
(arithmetic
or
character)
as
the
array
to
which it
is
assigned.
•
If
redimension specifications follow the array name,
the
rules
as
stated under
Redimensioning
Arrays
in
Chapter 3 must be followed.
