Combining Data Structures with Arrays
Placing Structure Variables in an Array
When there is a large volume of data in the same form, as with recipe data for different products,
structure variables can be placed in an array. This is used to create a database. In this case, the
structure variable becomes one record and each member becomes a field in the database.
Array S(x) of Structure Variables
S(1)
Member
A
S(0)
Member

C

C
For example, this can be used to specify the processing results for each production lot.
Example of Structure Variables in an Array: Product Processing Results (x)
