I am under the environment of DOS 7.1

::::::::::::::::::::::::::::::::::::::::::::::::::::::::
::Name: size_for.bat
::Usage: call size_for.bat %1
::Parameter: %1 is the size of the partition
::Function: Judge the partition of the hard disk. If it is greater than 4500, output "/NTFS"; if less than 4500, output "/-32"

set size=%1
set form=

if %size% GTR 4500 set form="/NTFS"


echo form = %form%

When I execute it, it prompts: syntax error

Which expert can help me give some pointers?

Thank you

You just look at how much the difference is between if /? in command and if /? in cmd

I'm under DOS 7.1, really can't figure it out

Because DOS has no comparison command at all.

Thank you. It seems a bit difficult.



Can't handle it, I won't eat.

I've been looking up information for many days, but I still can't find the answer.

The environment is: MSDOS7.1 environment,

The program of strings.com, for example, to judge the size of variables %a% and %b%: strings xx=sub %a%,%b%, and judge through errorlevel

Hello, can you give a hint?

strings m=sub %a%,%b%
if errorlevel 1 echo %a% is less than %b%

#The rule is like this: if the previous number is greater than the next number, the result of subtraction is assigned to variable m
#If the previous number is less than the next number, it will return errorlevel 1
