Symptoms
When certain COBOL files (for example, host definition files or existing assemblies) are imported in a Microsoft Host Integration Server 2010 environment, the host definition is not displayed in Transaction Integrator (TI) Designer. Instead, you receive the following error message:
Index and length must refer to a location within the string
Parameter name: lengthNote The host definition files and assemblies work fine when consumed.
Cause
This problem occurs because the parameter length is calculated incorrectly when you import the COBOL files.
