Member of Unicode Intrinsic Functions (PRIM_LIBI.IUnicodeIntrinsics)
Parameters

Details
AsBoolean converts a variable to a Boolean. By default, AsBoolean expects to receive a true or false string. Any other value will result in a runtime error. Optionally, you can override the defaults and specify the true and false values to be evaluated using the TrueCaption and FalseCaption parameters.
Example
In this example, Asboolean expects a string value of Y or N
#Button.enabled := #NChar.AsBoolean(N Y)
This is equivalent to writing
Case of_Field(#NChar) When (= Y) #Button.enabled := True When (= N) #Button.enabled := False Endcase
