You can compare two files on a remote system and copy changes
between the two files.
Before you begin
The Text Compare editor uses the Eclipse text editor to compare
two files. You can set preferences for text comparisons using the
Compare/Patch preference settings. To open this preference page, click
Window
> Preferences, then expand the
General list
item and click
Compare/Patch. Using the settings
on this page, you can, for example, select the
Ignore white
space option to control whether or not whitespace changes
are shown in the compare viewer. See the related topics for more information
on setting text comparison preferences.

When you compare
remote files from the Remote Systems view or the z/OS Projects view,
the compare editor performs several file checks to ensure that the
files you are comparing are fundamentally compatible:
- It checks the record format and record length parameters of the
two files and displays a warning if these parameters are different.
You have the option of continuing with the comparison or canceling
it.
- If you edit either file, it checks the length of each record and,
when you save the file, warns you if any record exceeds the maximum
record length.
- If you attempt to save a file with records that exceed the maximum
record length, it warns you that the records will be truncated and
gives you an opportunity to correct the records. The warning message
includes detailed information about line numbers that exceed the maximum
record length.
