In general, a documentation member is entered in edit mode unless any of the following is true, in which case the member will be entered in browse mode:
The user has entered the table in browse mode (via option B).
The documentation library has a record length greater than 80.
There are non-blank characters in a documentation line beyond column 71. In addition, the displayed line is truncated.
The documentation library is a Panvalet or Librarian library.
There are non-displayable characters in the documentation member.
Another user is viewing or editing the same documentation member. If profile variable SSCHBRO is set, see the chapter about IOA Administration in the INCONTROL for z/OS Administrator Guide for details.
Security access authorization to the documentation library does not determine or limit the mode (edit/browse) in which the documentation member is entered (similar to ISPF member checking).
