putpropq

putpropq( 
sl_id 
g_value 
S_name 
) 
=> g_value
sl_id->S_name = g_value 
=> g_value

Description

Adds properties to symbols or disembodied property lists. Identical to putprop except that S_name is not evaluated. If the property already exists, the old value is replaced with a new one.

putpropq corresponds to -> = as an assignment operator. So, obj->prop = value is equivalent to putpropq(obj value prop).

Arguments

sl_id	Symbol or disembodied property list.
g_value	Value of the named property.
S_name	Name of the property.

Value Returned

g_value

Value of the named property.

Examples

Both examples are equivalent expressions that set the property x on symbol s to 3.

putpropq('s 1+2 x)    
=> 3

y = 'x                
=> x

y->x = 1+2            
=> 3
