vm_set_oindent
The pre-defined function vm_set_oindent
sets the indentation
level used when printing nested structures. It has the following
prototype:
fun vm_set_oindent = (int<32> step) void:
where step specifies how much to indent when printing nested structures. This value typically translates into the number of white spaces (or tabs) used in terminals, but this must not be relied on since other printing media may interpret it differently.
