Pass argument when running script from command line

miguello

I have a JMP script that runs as a part of a larger script written in PowerShell.

I start the JMP script using

Start-Process -FilePath $JMP_path -ArgumentList ("`""+$JMPScriptPath+"`"") -Wait

I'd like to pass an additional argument to a script - just a text string.

How do I do that?

I tried just writing it into an Environmental variable, but while JMP can read it just fine when it runs as a standalone, it cannot read it when JMP starts from within PowersShell. I also would like to avoid writing this string into a file from Powershell script only to read it from JSL script. Maybe there is a way to pass that string to the script? Or maybe I should use Start-Process in a different way so that JMP could read Environmenta variable?

Can you show us how you are setting the environment variable?

This is working for me:

startjmp.ps1:

$JMP_Path = "C:\Program Files\SAS\JMPPRO\15\jmp.exe"
$JMPScriptPath = "C:\util\test.jsl";
$Env:ScriptArg = "Hello from PowerShell";

Start-Process -FilePath $JMP_Path -ArgumentList ("`""+$JMPScriptPath+"`"") -Wait

test.jsl:

Open Log();
myvar&nbsp;=&nbsp;Get&nbsp;Environment&nbsp;Variable("ScriptArg");
print(myvar);

Launched startjmp from PS

Log output in JMP:

Open Log();
myvar = Get Environment Variable("ScriptArg");
print(myvar);
/*:

"Hello from PowerShell"

Ok,

I'm doing it this way for now:

'myVariable = "{0}";' -f $variableToPassToJMP | Out-File "./paths.jsl"
Start-Process -FilePath $JMP_path -ArgumentList ("`""+$JMPScriptPath+"`"") -Wait
Remove-Item -Path "./paths.jsl" -Force -Confirm:$false

Not very elegant, but works

Upd.: Oh, in the JSL script itself I just do this:

Include("paths.jsl");

same idea, more or less:

Jmp.exe arguments

Yeah, I saw that post. As I said, JMP for some reason can't read environmental variable when launched from powershell script.

I actually set it up like this:

[System.Environment]::SetEnvironmentVariable('scriptArg', 'Hello From PowerShell', 'User')

...only because as far as I understand, when you set it up like this:

$Env:ScriptArg = "Hello from PowerShell";

it does not persist beyond powershell session, and when I was testing it by looking via Windows tools, I was getting some strange behavior. However, I don't even need it to persist beyond the session - within the session is perfectly fine, so I'll probably go back to your (and my initial) option, now that I tested it again.

Thanks!
