It works for macro coded functions:

-->ls1

it is possible to for scripts, transforming them into functions with no 
input nor output and then calling these function with exec

example:

Suppose you have a script foo.sce that contains some instructions (instr)
it is possible to create a function
function foo
instr
endfunction

the execution of the initial script can then be replaced by exec(foo). 
Warning calling just foo will also execute the script but into a 
temporary scope, which is destroyed at the end of the execution.
