Flex users who use Metalogic's FAMILYMANAGER product for their backup strategy can now compile rules for syntax using the SYSTEM/OPAL compiler, from CANDE, without having to use a RULES ENTER command.

As with DEFINE in ENTER files, the stand-alone compiler searches for the keywords ZAP, RELEASE, RIP etc. to signify the start of a rule definition. This allows new FLEX rules to be checked for syntax from a non-rules usercode without requiring a RULES ENTER command and is a significant step forward in rule development.

The files may be compiled under any usercode but must still enter the rules using the RULES ENTER command using the Rules Usercode and Accesscode.

For a rule to compile successfully, the same conditions employed by FLEX Inquiry apply i.e. there must be a message description enclosed in quotes after the rule type (this is handled as an OPAL string and is compiled), followed by a colon. The rule expression may appear on the same line. The expression MUST terminate with a semi-colon or the OPAL compiler will give a syntax error.
