Returns

Str

Example

"(Look ma, no parens)"[1..-1]  # "Look ma, no parens"

[]=(arr:Arr, range:NumRange, replacement:Arr)

Set array elements at specified indexes.

Change substring

Returns

replacement

Example

s="abcd"; s[1..3]="X"; s  # "aXd"

each(r:NumRange, cb:Fun) Source: stdlib.ngs:1344

Iterates over the elements of r, passing each in turn to cb.

Parameters

cb	Function to be called with values from r

Returns

r

Example

s=0
(1...10).each(F(i) { global s; s+=i })
