SET command

[RobNisbet]

Hi
I have a little piece of a batch file which works out the number of last month...however I am struggling to get the set command to work properly to remove 1 from the number.
Anyone able to make it work ?
Thanks..

for /F "tokens=2-4 delims=/- " %%A in ('date/T') do (
set MO=%%B
set Y=%%C
)
echo Month is %MO%
set /A M= ( %MO% -1)
echo Month is %M%
pause

Huh, as far as I tested your batch, it seems to work???
Result : MO=3 , M=2

Hi,
Thanks for responding ....but
I get a Missing Operard error, and M is blank.
Any ideas why ? (or an easier way of doing the whole thing?!)

Thanks !

Well, I cannot test it here, because ... it works here! Isn't that annoying ;-)

It sure is....
about the set command in isolation though ..
set /A %M= 8
works fine
set /A %M= (8+1) gives the error.

Is that the same with you ?

Cheers

You're not gonna believe it, but that also works here.

Try
set /A M= 8
set /A M= ( %M% +1)
echo Month is %M%

also

set /A M= 8+1
echo Month is %M%

Stranger still .. but resolved

set /A M= 8
set /A M= ( %M% +1)
echo Month is %M%
*this said invalid lala

set /A M= 8+1
echo Month is %M%
*but this worked

set /A M= 8
set /A M= %M% +1
*And this worked !!
which is the one I needed !

BUT when I put the string 08 from the date into M it doesnt like it.... any idea how to convert the string 08 into the number 8 ??

I am starting to think there must be an easier way to get the number of last month....??

Thanks..
