Controlling for variable

[sp2mf]

Hello! 

I am using PROC CALIS and attempting to specify the model in the image below based on the correlation matrix. I'm struggling to find syntax that controls for v3-v6 and then predict v1 from that. In other words, v2 is a covariate that I want to hold constant for v3-v6 to then predict v1. Does anyone have the syntax for this? I cannot find anything anywhere and its for my Masters thesis. Any help figuring this out would be extremely, extremely helpful. Thank you!!
