For each function, there is a list of the required and optional input arguments and output arguments, and a general description of how DBCHCL processes the function.

The interpretation of some of the arguments can depend on the setting of the DBCAREA set options. For instance, input/output string pointers can be variable strings. For output strings, DBCHCL will provide an address and length if Locate Mode is in effect; otherwise DBCHCL expects that the application has set the address of the area to which DBCHCL is to move the string. If DBCHCL detects an error while processing, various fields will be set to help the user interpret and handle the error.
