Character arrays
An element of a array character variable is a character string, for example,
T
is an array character variable with 3
elements:
T[1] = 'This is line one' T[2] = 'This is line two' T[3] = 'This is line three'
Array character variables can be defined with the
READ
command by entering more than one line number to read. For example:
READ\TEXT FILE.DAT/[1:5] T
creates array character variable T
with
5
elements. Array character variables can also be defined with a
character assignment, as above.
To specify the character elements of an array element of a array character
variable, use another set of brackets. For example, if
T[3]='abcdefghijkl'
then
T[3][1:10:2]
specifies characters
1, 3, 5, 7, 9
of array element 3
of the array
character variable T
, which is
'acegi
'. There is no maximum number of array elements for a
character variable. There is no maximum character length for an
array element.
