**call**(*f*,*A*). **A** being a vector, evaluate **f(A[1],...,A[#A])**.
**call**(*f*, *A*). *A* being a vector, evaluates *f*(*A*[1], ..., *A*[#*A*]).
Remark. Unlike **apply**, **call** can be used if the function **f** needs several arguments. For example :
**Remark**. Note that, if #*A*=1, **call**(*f*, *A*)=**apply**(*f*, *A*)[1]; but unlike **apply**, **call** can be used if the function *f* needs several arguments. For example:
>? printc(x[..])=call(printsep,[":",x]);
>? printc(1,2,3)
>1:2:3
or
>? call(idealprimedec,[nfinit(x^2+1),3])
>%1 = [[3, [3, 0]~, 1, 2, 1]]
