3.2.1 Vertical Arrays (m x 1)

A vertical array is simply an array that is 1 value wide and M values deep. M can be defined in the FSML code or can be read from the input file. In the simple example below, the value of M is read from the file and that value, defined as numships, is used to count through a loop three times.

For a more complex example of vertical arrays, see the loop example in Section 3.3. In the loop example, the data is arranged in a multi-column data file. The data is processed as three vertical arrays, each of which is 101 records long.
