Explanation of using AIM via Batch

aim_explanation.bat

Your batch script is currently: 
=========================== 
set scmd="C:\Program Files (x86)\CyberArk\ApplicationPasswordSdk\CLIPasswordSDK.exe" password /p AppDescs.AppID=APP_AIM-TEST /p query=Safe=LNC-CMOD_DF_T;Folder=Root;Object=ARSTLOD /o Password 

for /f %%A in ('"%scmd%"') do @echo pass is: %%A 

arsload -fnv -u ARSTLOD -p %scmd -h ondemand-test.lnc.lfg.com,1444 -g %1 -a %2 %3 
==================================== 

It should be: 

==================================== 
set scmd="C:\Program Files (x86)\CyberArk\ApplicationPasswordSdk\CLIPasswordSDK.exe" password /p AppDescs.AppID=APP_AIM-TEST /p query=Safe=LNC-CMOD_DF_T;Folder=Root;Object=ARSTLOD /o Password 

for /f %%A in ('"%scmd%"') do arsload -fnv -u ARSTLOD -p %%A -h ondemand-test.lnc.lfg.com,1444 -g %1 -a %2 %3 
============================== 

%scmd% is basically the function within this batch script. It's not the variable that's storing the password, even though it would appear that way at first glance. We're actually setting a string of code into the %scmd% variable to be run later when called upon. 

Later comes when we want to get the Password and place it in the %%A object. In your current script, you just echo this out as "Pass is: password123" and that's the end of the script... until it sees your arsload and continues on doing that with an invalid and null %scmd variable. 

In mine, instead of echoing the password, we're passing it off to your arsload method.
