I would like to pass a tag value into a SP with the call.registerInParam and I do not know the syntax.  
Something simple, I’m sure.

`
myValue = system.tag.getTagValue("[default]MyTag")`

Thanks,  
So, a two step process? No way to specify the tag itself in the call.registerInParam?

mwaynesmith, you can make it one line of code:

`call.registerInParam("arg_one", system.db.INTEGER, system.tag.getTagValue("[default]MyIntTag").value)
`

… but you will still need to read tag value - it is value, not the tag that you want to pass. So yes, a 2-step process.
