This command will change the dimensions of an array.
Format
REDIM <ARRAYNAME>(<SIZE>) REDIM <ARRAYNAME>(<ROWS>,<COLUMNS>) REDIM <ARRAYNAME$>(<SIZE>) REDIM <ARRAYNAME$>(<ROWS>,<COLUMNS>)
Parameters
<SIZE> = new number of entries in a single dimension array.
<ROWS> = new number of rows in a two dimensional array.
<ROWS> = new number of rows in a two dimensional array.
<COLUMNS> = new number of columns in a two dimensional array.
Example
This example shows how to change a one dimensional numeric array.
Example
This example shows how to change a two dimensional string array.
10 DECLARE STRING NAMEAGES$(3,2) 20 LET NAMEAGES$(1,1) = "Abraham" 30 LET NAMEAGES$(1,2) = "Lincoln" 40 LET NAMEAGES$(2,1) = "Dwight" 50 LET NAMEAGES$(2,2) = "Eisenhower" 60 LET NAMEAGES$(3,1) = "Theodore" 70 LET NAMEAGES$(3,2) = "Roosevelt" 80 REDIM NAMEAGES$(5,2) ! Make room for more
Comments
The
REDIM
must have the same number of dimensions as the original declaration of the array.
  • If the array has two dimensions, the second array bound cannot change. It must have the same value as the original declaration.
  • If
    REDIM
    makes an array smaller, elements (or rows, for a two dimensional array) at the end of the array are discarded.
  • If
    REDIM
    makes an array larger, elements (or rows) are added at the end of the array, and initialized as they would be with a
    DECLARE
    .
This can be an interactive command that takes effect as soon as it is received by the printer, or a program command that is preceded by a line number.
