The document template created is checked. The system creates a structure file in ASCII format that contains all control objects in the template (with the exception of character sizing objects).

The syntax checks on the structure file are as follows:

• Analysis of the structure file (finds symbols and control data)
• Check for all symbols and their parameters
• Check for all repeating groups and their parameters
• Check for all symbol nesting
• Creation of error log
• Saving the structure information

The structure information is not stored until the check routine has been completed.
