Eval

Description

Evaluates whether an object meets the specified search criteria.

When used with record criteria, it will determine whether a specific record is attached to the object; if used with record-field criteria, it will return the value of the field as a REAL value.

FUNCTION Eval(
				h : HANDLE;
				c : CRITERIA): REAL;

def vs.Eval(h, c):
    return REAL

Parameters

Name	Type	Description
h	HANDLE	Handle of object to which the search criteria will be applied.
c	CRITERIA	Search criteria.

Examples

VectorScript

hasRecord:=Eval(handleToObject,(R IN ['Part Info']);

Python
