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.
