HELP-PROMPT: This is the global node for which the data is given
DESCRIPTION: This field contains a global node (lacking the beginning'^') for the MERGED TO entry in the current file (TO FILE#, #.01). The global prior to the merge can be reconstructed by setting the value in field #1.01 of
the subfile into the global location specified by the data in the current field (#.01). If there is no field #1.01 associated with a global location, the value was NULL.
