We want to magnetic encode variable length information.
Above you see an example for a magnetic encoder, Match-Key1 to 3 is the information to be sent to the magnetic writer. Note that it begins after the start sentinel but ends on the end sentinel (?). This is to allow variable record lengths and ‘?’ is taken as end of message. Note also that the length, e.g. 78 is the max. characters you can send to track1.
In the magnetic encoder mode and encoding variable lengths, you have to add –pad to reader0 in D:\EditorGT\user\sytem\arguments.txt
