|func_desc=Sets the prims parameters according to '''rules'''.
|func_footer=This is a very powerful & sharp function, each rule takes at least one parameter and has its own quirks. Each PRIM_* rule has its own dedicated article with specific information.

|caveats=
*Scripts written before September 2004 that use [[PRIM_TYPE]] depend on PRIM_TYPE to have the value 1; if these scripts are recompiled, the new value of {{HoverText|PRIM_TYPE|Value: 9}} will be used causing errors at runtime.
**To fix this replace the PRIM_TYPE flag with the value 1 or updated to the newer PRIM_TYPE syntax.
* [[PRIM_ROTATION]] is bugged in child prims, see [[llSetPrimitiveParams#Useful_Snippets|Useful Snippets]] for a workaround, or the linked SVC-93 issue below.
* This function will return an error if fed data of the wrong type. This is problematic when feeding data into it from user input or notecard. To remedy this, see this List Cast function: [[list_cast]]
