FUNCTION xpfCastValue (value : GENERIC;
newDatatype : INTEGER)
castedValue : GENERIC;
Use this function to cast a value to another type avoiding run-time conflicts in assignments. E.g. from INTEGER to xpxDateTime and back, from Instance or aggregate Id to INTEGER and back, LOGICAL to BOOLEAN, REAL to INTEGER, etc. See also specialized functions like xpfIntegerToInstanceId, xpfIntegerToAggrId

Return Value
| Type | Name | Comment |
| GENERIC | castedValue | comments |
