Resolve External Action Blocks

External action blocks define the interface between CA Gen procedure steps or action blocks and handwritten subroutines. You use external action blocks to access subroutines that were created outside CA Gen. You must compile any external action blocks outside the CA Gen software. This must be done before you install the CA Gen procedure step or action block that uses the external action block. If not, you will receive an unresolved external reference error condition.

For more information about how to code external action blocks for use with a CA Gen application, see the chapter “Using External Action Blocks.”

Note: The installation process accesses software other than CA Gen. Errors during installation can occur from these other software applications, such as compilers, or from the operating system itself.
