Language Specifications
-----------------------
DAL is a complete language for describing connectivity tasks. DAL consists of these statement groups:
- Host Connection Statements
These establish and terminate a connection to a host system in the network, providing concurrent access to multiple hosts running DAL Servers.
- Data Manipulation Statements
These offer complete ANSI standard level 1, SQL-based data access to host databases and files.
- Program Structure Statements
These support testing, looping, and procedure calls within a DAL program.
- Output Statements
These generate output messages from the DAL program. The client application processes these messages.
