# LogiView

## Userexit Call

| LogiView enables calling userexits (DataView standard userexits and other C functions specified in the Include file "usrexi.h") from a decision table. Calling a userexit returns - analogue to the call of an Integer function - an Integer value as a result. The call can either be performed as an action (in terms of an allocation) or as a condition (in terms of a comparison) and as an argument when calling a decision table/procedure respectively other functions.
| If LogiView is started again by using a userexit call, the userexit call may not provide the correct return value in the decision table!
