variable individualy constants & initialized value

Code:

macro setlocaloverrides [name,defailts,defvals] { macro name args& \{ match defailts,defvals \\{ name args \\} \} }
macro init1 [arg] { macro arg args:=1 \{ arg args \} }
macro init0 [arg] { macro arg args:=0 \{ arg args \} }

set individualy constants "lin=1", "mov=0", "6=2" that may presence in expression that variable hello is equal

Code:

setlocaloverrides hello,lin mov 6,1 0 2

set short form initialized as 1

Code:

init1 hello

Code:

hello;hello=1
hello = lin*mov+6;hello=1*0+2
; at here there is no such constants as lin and mov, constants are realy variable expression individualy
lin =0
lin =5
lin equ (1 shl 5)
mov equ 7
hello = lin*mov+6;hello=1*0+2
hello2 = lin*mov+6;hello2=(1 shl 5)*7+6
restore lin
hello = lin*mov+6;hello=1*0+2
hello3 = lin*mov+6;hello2=5*7+6
hello equ lin*mov+6;hello equ 1*0+2
hello equ hello*2;hello equ 1*0+2*2

by the way init1 init0 are limited to be used on assembly time variables
but setlocaloverrides has no such limitation it could be applied to any macro and case of assembly time variable is only one of numerous implementations
init1/init0 & setlocaloverrides could be combined together on some assembly time variable, or applied separatedly.

If someone wish to apply such weird syntax these 3 lowweight macros (or one of them) will help.
init1 & init0 could be replaced with

Code:

macro init [arg,def*] { macro arg args:=def \{ arg args \} }
