EVAL_EXPRESSION

The command EVAL_EXPRESSION evaluates a core expression without the need of an EXPRESSION attribute.

Syntax

CC "Core" EVAL_EXPRESSION coreExpr [ objid:idValue | modelid:intValue ]

#-->RESULT ecode:intValue result:value

Parameters

• <main-parameter (strValue) - coreExpr, is a string containing a core expression.
• objid (idValue) - id of an object if the expression is object-related
• modelid (idValue) - id of a model if the expression is model-related

Returns

• ecode (intValue) - Contains the error code or is 0 in case of success.
• result(anyValue) - is the same type as the expression's result type and contains the expression's result. If the command failed result is of type STRING and contains an error message.
