    <p>This topic is interesting! Perhaps you, like me, find confusing and annoying the output format of FC command, although it provides the required information indeed. The Batch program below take the output of FC command and rearrange it in a way that allows to identify if a new block of information has been added between two lines of original file, or if a block of lines has been deleted from the original file, or any other case of file modification (updated). The most difficult part was to choose the format to display the information in a pleasant way, but I think my solution is pretty good!</p> <pre><code>@echo off rem FCOMP.BAT: Format FC output in a pleasant way rem Antonio Perez Ayala if "%~2" neq "" goto start echo Format FC output identifying added, deleted or updated sections echo/ echo FCOMP filename1 filename2 [/switches /for /FC /command] goto :EOF :start setlocal EnableDelayedExpansion set while=if not set do=goto endwhile set endwhile=goto while set "space= " set "spaces39= " fc %3 %4 %5 %6 %7 %8 %9 %1 %2 &gt; differences.txt if %errorlevel% equ 1 call :FormatFC &lt; differences.txt del differences.txt goto :EOF :FormatFC set /P line= set /P line= rem Process each set of differences :while %while% defined line %do% rem Load old and new sections of this set set line= set /P line= set old=0 :while1 %while% "!line:~0,5!" neq "*****" %do%1 set /A old+=1 set oldLine[%old%]=!line!%spaces39% set line= set /P line= %endwhile%1 :endwhile1 set line= set /P line= set new=0 :while2 %while% "!line:~0,5!" neq "*****" %do%2 set /A new+=1 set newLine[%new%]=!line!%space% set line= set /P line= %endwhile%2 :endwhile2 rem Identify the type of this set if %old% equ 2 ( echo ====== NEW SECTION ADDED ==================================================== echo/ echo(!oldLine[1]:~0,79! set /A new-=1 for /L %%i in (2,1,!new!) do echo( ^|!newLine[%%i]:~0,70! echo(!oldLine[2]:~0,79! ) else if %new% equ 2 ( echo OLD SECTION DELETED ========================================================== echo/ echo(---------!newLine[1]:~0,70! set /A old-=1 for /L %%i in (2,1,!old!) do echo -!oldLine[%%i]:~0,78! echo(---------!newLine[2]:~0,70! ) else ( rem both %old% and %new% gtr 2 echo ============================== SECTION UPDATED ============================== echo/ if %old% lss %new% ( for /L %%i in (1,1,%old%) do echo(!oldLine[%%i]:~0,39!^|!newLine[%%i]:~0,39! set /A old+=1 for /L %%i in (!old!,1,%new%) do echo(%spaces39%^|!newLine[%%i]:~0,39! ) else ( for /L %%i in (1,1,%new%) do echo(!oldLine[%%i]:~0,39!^|!newLine[%%i]:~0,39! set /A new+=1 for /L %%i in (!new!,1,%old%) do echo(!oldLine[%%i]:~0,39! ) ) rem Pass to next set of differences echo/ set /P line= set line= set /P line= %endwhile% :endwhile exit /B </code></pre> <p>Antonio</p>

    1. CO+1 - Nice Aacini. Can you document the options a bit. I assume the /switches are options for the FC, but I haven't a clue about the other options (/FOR, /FC, /COMMAND). I like the output format, except updates are hard to understand if they occur at the end of a long line. I don't have any suggestion, other then to allow displayed length to exceed 80 chars.

    3. CO@dbenham: Thanks, Dave! The options should just read: `[FC switches]`. I am working now trying to solve the problem of long lines...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
