You have any comparison tools to SD> recommend (DOS or OS/2, doesn't matter)? i generally used "comp /b" (/b for binary compare instead of textual) but i don't know what version of comp that is/was... i don't see it as a built-in in 4DOS or 4OS2... i'm lookin'... [time passes] i can't find it, now... the comp that i do find is comp.com and is both OS/2 and DOS flavored (one .com file for both)... maybe it was "fc"?? i just know that i had to use the "/b" option to denote a binary comparison instead of a textual one... damn, that's got my goat and i'm rather frustrated that i can't locate that tool or remember exactly which one it was :( maybe it was... hummm... :!: [time passes] found it!! believe it or not, on one of the win98se boxes hiding out in \windows\command and also in \options\tools\oldmsdos... this last one is a copy of the tools\oldmsdos folder from the win98 install cd... it is FC.EXE... [/me quickly copies it over to this OS2 box and gives it a try] aww... says incorrect DOS version :? now, how to setver on warp3 with 4DOS?? :( maybe that's why i still tend to do most development on that machine?? no... can't be because i've been running this one for far too long... there's gotta be another util that i used to use that i probably lost yers back when i had to reinstall this system :? dagnabit! it was a very very very handy tool, too... guess i need to figure out how to hack it and blow the dos version check out :? :( well, in any case, here's the /? output just so's you have an idea what it is/was capable of and decide to go looking for a similar tool on the net somewhere... FC [/A] [/C] [/L] [/LBn] [/N] [/T] [/W] [/nnnn] [drive1:][path1]filename1 [drive2:][path2]filename2 FC /B [drive1:][path1]filename1 [drive2:][path2]filename2 /A Displays only first and last lines for each set of differences. /B Performs a binary comparison. /C Disregards the case of letters. /L Compares files as ASCII text. /LBn Sets the maximum consecutive mismatches to the specified number of lines. /N Displays the line numbers on an ASCII comparison. /T Does not expand tabs to spaces. /W Compresses white space (tabs and spaces) for comparison. /nnnn Specifies the number of consecutive lines that must match after a mismatch. i'll keep looking, too because a good file comparison tool is a must for many programming situations... especially if you have large (greater than 64K) files to compare :) )\/(ark * Origin: (1:3634/12) .
