# Using an array instead of a message structure - intrepidcs API

In some programming environments (such as [LabVIEW](/neovi-api/basic-operation-intrepidcs-api/using-the-api-in-labview-intrepidcs-api.md)) it maybe inconvenient for you to access the [message with a structure](/neovi-api/win32-api-overview-intrepidcs-api/structures-types-and-defines-overview-intrepidcs-api/setting-structures-overview-intrepidcs-api/message-structures-neovi-api.md). In these cases you may use a byte array in place of the structure. Table 1 below lists the locations of message items in the byte array for a 64 bit version of the structure. The message structure is 8 byte aligned. Padding bytes are marked in black.
