When System Architect opens an encyclopedia and parses its SAPROPS.CFG file and USRPROPS.TXT, it checks the syntax in the statements.
Any syntax errors are displayed in an Error dialog.

Information in the dialog box
In addition to any error message, System Architect places further information in the error dialog about the syntax error found, as follows.
while checking a DEFINITION command
while checking a DISPLAY command
while checking a LIST command
while checking a VALUE command in a LIST
while checking a PROPERTY command in a DEFINITION
while checking for a DEFINITION or LIST command
Would you like to continue?
Example
The entire error message might look like this:
Unknown property DISPLAY type < > while checking a DEFINITION command.
Maximum number of lists is 400. This includes SAPROPS and USRPROPS, where the number of lists actually used from the SAPROPS is dependent on the Encyclopedia Configuration.
Maximum number of properties for one Diagram, Symbol or Definition is 128
Maximum number of VALUES in a LIST is 128.
Runtime edits
Runtime is the time when you are drawing diagrams, and, in particular, when you are making encyclopedia entries. The dialogs displayed when you add or modify the dictionary are under control of SAPROPS.CFG and USRPROPS.TXT; the EDIT commands act to prevent the user from making erroneous entries. For example, assume SAPROPS.CFG has the following entry:
PROPERTY "My Property" { EDIT numeric LENGTH 2 MINIMUM 1 MAXIMUM 32 }
In this example, an “Invalid Value” message appears if you type AB or 0 in the “My Property” text field. This happens because the property has been specified as a numeric (that is, it cannot contain letters), of minimum value 1.
System Architect performs the following runtime edits:
