Returning Values via References

Let the caller determine how to return the function result and avoid the need of dedicated variables.

Description: Instead of using "global" variables for return value, the function can use one of it`s arguments as variable reference. The caller can then pass a variable name to the function and the function can store the result into this variable making use of the command line expansion of the command processor:

Note: The var1 variable is not reserved for this articular function. Any variable can be passed to the function the caller has full control.

Usage:

1. 2. call:myGetFunc var1 echo.var1 after : %var1%

Script:

1. 2. 3. :myGetFunc - passing a variable by reference set "%~1=DosTips" goto:eof

Script Output:

Script Output

var1 after : DosTips
