Compression strength can be determined for other box material and size combinations by editing the Table of Regular Slotted Containers. In specifying a material code names like 275C, 275c, and 275 C would be interpreted as three different codes. Use the MS-DOS text editor to view the data in file RSC.BSE. From the CODE41 Main Menu enter Program RSC and RSC Input. Then edit the data to appear like the left hand side shown below.

You will notice that comment statements have been added to the data base. Program RSC is written to recognize and skip over misformatted lines and blank lines. Therefore comments can be added to conveniently segregate the data. Exit the editor and execute RSC as was performed in Example 1.1

This example is intended to show how box strength might vary with relative humidity (RH). It is shown in Example 2.2 how the stress-strain properties for materials 275CB and 275BC were hypothetically defined in terms of the properties of components at laboratory conditions of 73^o F and 50% RH. Materials 90%CB and 90%BC are the same as 275CB and 275BC, respectively, except that their outer linerboards were assigned properties at 73^o F and 90% RH. Strength is shown to decrease as a result of the assumed affect of RH and, more significantly, the ordering of strength from BC- to CB-flute construction is now reversed.
