When editing a map in MAPC, error message DC365434 is possible if the access is via a UCFTSO connection.
Release: All supported releases.
In the SYSGEN OLM statement, FIELD START CHARACTER is set to x'1E'.
This is not possible under UCFTSO because it will be interpreted as a command delimiter.
In the SYSGEN OLM statement, change FIELD START CHARACTER to x'7C'. This change will not impact existing maps. The FIELD START CHARACTER is only relevant during map editing.
