sas - Encoutering an error 'run executed for function module' while calling function -

i wrote 1 module in proc iml , trying call using call fuctiong , supplied parameters.

but throwing erorr: run executed function module.

any suggestion?

the error message says have defined function returns value ('function module') need call this: x = myfunction(x,y,z);

you cannot use call statement call function, call subroutines not return values.
