The nice thing about functions is that you can return the error code of your function giving you the following syntax
IF myfunc(var1,var2,var3) THEN * process errors END which i prefer to CALL mysub(var1,var2,var3,error) IF error THEN * process errors END and beware that parameters passed through to your function is still passed 'by reference' like in a subroutine, and not 'by value', so your function is able to alter all passed parameters if you want to restrict your function from altering the passed parameters you still need to enclose them in () best regards from 'grey rainy' Denmark Jeff wrote this : > Functionally speaking, why would I use a function which can > return a single > argument when I can use a subroutine which can return 1 or > more?
