This repo is for the SPSS syntax used for the PHS Source Linkage File (SLF) project.
Access to the linkage files is usually only granted to members of the LIST or H&SC teams within PHS.
Most documentation for the SLFs can be found on the internal PHS network: \\Freddy\DEPT\PHIBCS\PHI\Health & Social Care\Topics\Linkage\Reference Documents\
There is an FAQ document which you can find in the location mentioned in the documentation section. If that doesn't answer your question please get in touch, either by email or through Microsoft Teams on the Source Linkage File Team
