The following table describes the supported castings in each ABL parameter mode (INPUT and OUTPUT) between the ABL LOGICAL type and XML Schema.

Table 1. ABL data type cast—LOGICAL
For this XML Schema type . . . In this ABL parameter mode . . . OpenEdge . . .
string normalizedString INPUT Serializes the ABL parameter into the SOAP request message according to the XML Schema serialization rules.
OUTPUT De-serializes the XML Schema string type as if it was a serialized boolean value.
boolean INPUT Serializes the ABL parameter into the SOAP request message according to the XML Schema serialization rules.
OUTPUT De-serializes the XML Schema value into the ABL parameter according to the XML Schema serialization rules.
decimal float double INPUT Serializes an ABL LOGICAL value of true to an XML Schema type value of 1, and serializes a LOGICAL value of false to an XML Schema type value of 0.
OUTPUT De-serializes an XML Schema value of 0 to an ABL LOGICAL value of false, and all other XML Schema values to a LOGICAL value of true.

 INPUT Serializes an ABL LOGICAL value of true to an XML Schema type value of 1 (or -1 for a nonPositiveInteger), and serializes a LOGICAL value of false to an XML Schema type value of 0.
OUTPUT De-serializes an XML Schema value of 0 to an ABL LOGICAL value of false, and all other XML Schema values to a LOGICAL value of true.
