The imsLogID build descriptor option specifies an identifier that will be included in records written to the IMS™ log. The identifier is a 2-digit hexadecimal number from A0 to FF.
The record is written in response to errors that occur in the run unit. For details on the format of the log record, see the documentation for Rational® COBOL Runtime for zSeries, which is on a website referenced in Sources of additional information on EGL.
The setting for imsLogID is effective only if specified for the first program in the run unit. If you do not specify a value for imsLogID, no runtime errors or diagnostic information is written to the IMS log for that run unit.
