Windows Batch Scripting

Set Environment=%1
Set Reportid=%2
Set ReportInstance=%3
SET InputParameters=%4
SET OutputFilename=%5
SET PRINTREPORT=%6

First Three parameters Mandatory and next three are optional. How do I write windows batch script so that user may or may not pass 4,5 and 6 parameters. Any help is appreciated.

Giovanni

Just create your script to account for omission of these parameters.

For example:

if not [%4]==[] (
     echo Process InputParameters
)
if not [%5]==[] (
     echo Process OutputFilename
)
if not [%6]==[] (
     echo Process PRINTREPORT
)

I did not address this issue properly say I have .bat file and I want to run a.bat with named parameter Environment="AAA" Reportid=4 ReportInstance="LLL" InputParameters=
OutputFilename= PRINTREPORT=Yes. and my output should be
Environment=AAA
Reportid=4
ReportInstance=LLL
PRINTREPORT=Yes

If I passs a.bat Environment="AAA" Reportid=4 ReportInstance="LLL" InputParameters=test
OutputFilename= PRINTREPORT=Yes my output should be
Environment=AAA
Reportid=4
ReportInstance=LLL
InputParameters=test
PRINTREPORT=Yes

Any idea how to write batch script

Giovanni

This will get you closer...

script.bat Environment="AAA" Reportid=4 ReportInstance="LLL" InputParameters=test OutputFilename="" PRINTREPORT=Yes

Output:
[ENVIRONMENT]=[AAA]
[REPORTID]=[4]
[REPORTINSTANCE]=[LLL]
[INPUTPARAMETERS]=[TEST]
[PRINTREPORT]=[YES]

The position of the argument makes no difference. Currently this is case insensitive and null values either need to be enclosed in quotes or the arg omitted altogether.

@echo off
setlocal enabledelayedexpansion
set args=%*

for %%z in (Environment Reportid ReportInstance InputParameters OutputFilename PRINTREPORT) do (
	call :arg %%z
	if [!found!]==[true] (
		echo [!option!]=[!value!]
	)
)
goto :eof

:arg
set c=1
set arg=%1
call :UCase arg
for %%a in (!args:=^= !) do (
	set str=%%a
	call :UCase str
	if [!arg!]==[!str!] if [!c!]==[1] set option=!str!
	if [!c!]==[2] if [!arg!]==[!option!] (
			set value=!str:"=!
			if not [!value!]==[] set found=true
			goto :eof
	)
	if [!c!]==[2] set c=0
	set /a c=c+1
	set found=false
)
goto :eof

:LCase
for %%i in ("A=a" "B=b" "C=c" "D=d" "E=e" "F=f" "G=g" "H=h" "I=i" "J=j" "K=k" "L=l" "M=m" "N=n" "O=o" "P=p" "Q=q" "R=r" "S=s" "T=t" "U=u" "V=v" "W=w" "X=x" "Y=y" "Z=z") do call set "%1=%%%1:%%~i%%"
goto :eof

:UCase
for %%i in ("a=A" "b=B" "c=C" "d=D" "e=E" "f=F" "g=G" "h=H" "i=I" "j=J" "k=K" "l=L" "m=M" "n=N" "o=O" "p=P" "q=Q" "r=R" "s=S" "t=T" "u=U" "v=V" "w=W" "x=X" "y=Y" "z=Z") do call set "%1=%%%1:%%~i%%"
goto :eof

Thanks for you solution. Is there any way can I set a each value to a variable so that these values can be in other program. I mean is it possible to say SET ENVIRONMENT=AAA
SET REPORTID=4
SET REPORTINSTANCE=LLL
SET INPUTPARAMETERS=TEST
SET PRINTREPORT=YES

Giovanni

Yes, just create a new var as needed :

call :arg Environment
if [!found!]==[true] (
     set Environment=!value!
     echo Environment=!Environment!
) else (
     echo Environment argument is required, aborting.
     goto :eof
)

Is it possible to send full script together so that I will execute. Thanks a lot

Everything works perfectly as you said.One question When pass ENVIRONMENT=Dev32 script is not working since it looks for call :check Environment and program assumes it is case sensitive. Is there any way could we ignore case sensivity?
