The error codes on the left below can be translated into the text on the right with the AQL message function, described previously. Some of these error messages relate to problems within the AQL interface that cannot be corrected by the user. These may arise due to errors within the AQL code, corrupt Aqwa files, or lack of resources such as free memory or file handles.

The DLL makes use of several standard Aqwa routines for file access, and these may generate error messages that are not covered by the codes above. In this case the Aqwa error messages are echoed to the spreadsheet. They were not intended for outputting to a spreadsheet, because they are usually too long for the cells, so it is necessary to enlarge the cell so that the message can be read.
