Question: What is the easiest way to copy one array into another? Without using a loop!
Direct assignment is unfortunately not possible: t()=s()
“Array Insert” is only for multidimensional arrays?!
Or am I missing something here? “Array Insert t(), ,s()” doesn't work either.

manual page 139

Quote MATH SCALE in(), scale,out()
This scales the matrix in() by the scalar scale and puts the answer in out().
Works for arrays of any dimensionality of both integer and float and can
convert between. Setting b to 1 is optimised and is the fastest way of copying
an entire array.

Thanks, works! I hadn't even considered MATH ...
Read it right away :-)

Found an other way in the manual (but didn't try):

Quote ARRAY ADD in(),value,out()

This adds (or appends for strings) the value 'value' to every element of the
matrix in() and puts the answer in out(). Works for arrays of any
dimensionality of strings and both integer and float (can convert between
integer and float). Setting num to 0 or “” is optimised and is a fast way of
copying an entire array. in() and out() can be the same array.

This is also "more obvious" because it is also an 'ARRAY' command.

So @homa: You looked just 1 "table line" too far down..

Sometimes examples are more helpful than reading manuals!
@bfwolf Further exciting findings:

Dim integer s(9)=(5,1,3,4,7,7,3,0,0,1),t(9)
Dim integer x,i
Math v_print s()
x=Math(max s(),i)
Print x,i
Array Add s(),0,t()
Math v_print t()
Array Add s(),-1,t()
Math v_print t()
Array Set 0,t()
Math v_print t()
Math scale s(),1,t()
Math v_print t()
