Creati ng a Branch Version
You can create a branch version of a file by editing a version that has been previously
edited. A branch version is simply a version with an SID that contains a branch and
sequence number.
For example, if version 1.4 already exists, the command
get -e -r1.3 s.demo.c
retrieves version 1.3 for editing and gives 1.3.1.1 as the proposed SID.
In general, whenever get discovers that you wish to edit a version that already has a
succeeding version, it uses the first available branch and sequence numbers for the
proposed SID. For example, if you edit version 1.3 a third time, get gives 1.3.2.1 as the
proposed SID.
You can save a branch version just like any other version by using the delta command.
Retrieving a Branch Version
You can retrieve a branch version of a file by using the -r option of the get command.
For example, the command
get -r1.3.1.1 s.demo.c
retrieves branch version 1.3.1. 1.
You may retrieve a branch version for editing by using the -e option of the get
command. When retrieving for editing, get creates the proposed SID by incrementing
the sequence number by one. For example, if you retrieve branch version 1.3.1.1 for
editing, get gives 1.3.1.2 as the proposed SID.
As always, the command displays the version number and file size. If the given branch
version does not exist, the command displays an error message.
You may omit the sequence nu mber if you wish. In this case; the command retrieves the
most recent branch version with the given branch number. For example, if the most
recent branch version in the s-file s.def.h is 1.3.1.4, the command
get -r1 .3.1 s.def.h
retrieves version 1.3.1.4.
