I am trying to duplicate the following UNIX command in Windows XP DOS

mode:

 

set WFHM_DATE=`perl Calc_Prior_Work_Date.pl`

 

which would set the WFHM_DATE to the value of 20070703 (when run on

July 5th, 2007). I am running a third party software package that

supports a DOS mode which is the only place I can manipulate the

environment variables on-the-fly.

 

I have tried doing 'perl Calc_Prior_Work_Date.pl | set WFHM_DATE='.

It did not work.

 

Any ideas?

Every process you launch in Windows inherits its environmental

variables from its parent. If it modifies them then these changes

are not passed back to the parent.

 

To modify environmental variables globally you can use one of

these tools:

setx.exe (Win2000 Resource Kit)

setenv.exe (ftp://barnyard.syr.edu/pub/vefatica/setenv.exe)

 

Note that the change will affect all new processes but not

pre-existing ones.

 

By the way: "DOS" is an operating system, same as Unix. When

you say "DOS mode" you probably mean the Command Prompt.

Correct. I don't have setx available on my machine. I did find a

solution that is working for me in another thread. It boils down to

this:

 

 

for /f "tokens=*" %%a in ('perl perl/Calc_Prior_Work_Date.pl') do set

PRIOR_DATE=%%a

 

set yy=%PRIOR_DATE:~0,4%

set mm=%PRIOR_DATE:~4,2%

set dd=%PRIOR_DATE:~6,2%

 

 

The perl program is (all comments removed):

$| = 1;

use strict;

use diagnostics;

use Date::Manip;

main: {

Date_Init('TZ=US/Central', 'GlobalCnf=perl/Holidays.dates');

my $date = $ARGV[0] || 'today';

my $diff = Date_IsWorkDay($date);

$diff = 0 if (defined(Date_IsHoliday($date)));

print STDOUT &UnixDate(&Date_PrevWorkDay($date, $diff), '%Y%m%d');

exit 0;

}

 

The Holidays.dates file is:

*Holiday

1/1 = New Year's Day

Last Monday in May = Memorial Day

7/4 = Independence Day

First Monday in September = Labor Day

Fourth Thursday in November = Thanksgiving Day

12/25 = Christmas Day

I am so sorry, Pegasus. I forgot to thank you for your help.

You're welcome. And as I said, setx.exe comes with the Windows

Resource Kit.
