Who Can Use Data Access Routines?

Within this manual, the term user refers to a user of a DARs application program. He will of necessity also be a Marine user. The term programmer refers to the programmer who calls DARs routines in an application program.

The programmer is expected to be familiar with Marine and proficient at FORTRAN 77 programming. The user does not need any programming knowledge, providing the programmer makes his program sufficiently user-friendly.

AVEVA can provide consultancy services to assist customers in the preparation of applications programs. The experienced programmer, however, will find DARs no more difficult to use than other well-written library packages.

To assist the programmer in his program development, a monitor option may be selected to obtain information on entry to and exit from each data access routine.

An Marine user identification and password will be needed to use an application program and the privilege of the user will be checked before any action is performed.
