Hi Folks -

I am building a process that requires me to extract the year from a file name.

The file name is as follows:

hp_profitandloss_extract_FY08.csv

The year will always be the last string preceeding the .csv.

I need to extract the year and set it in a variable and also set another variable that is 1 less. I run into an issue with batch subtraction when there is a leading zero. Is there an eays way around this?

This is what I have and works fine, except when encountrring a leading zero:

SET "DATAFILENAME=%~1"
SET "ENDYEAR=%DATAFILENAME:~-6%"
SET "ENDYEAR=%ENDYEAR:~0,2%"
SET /A "STARTYEAR=%ENDYEAR%-1"

SET "STARTPOV=Sep-%STARTYEAR%" & SET "ENDPOV=Oct-%ENDYEAR%"

echo %STARTYEAR%
echo %ENDYEAR%
pause

Thanks!

Been covered dozens of times on the forum if you search.

Put a 1 in front of the number so that it become 108. Then subtract 1. Then substring the last two positions.

HI Squash -

Ah yes, very easy!

This solves for my issue, but looks awfully clunky.
