the below is one much better language

<< top=0,  size=4,  arr=8, notUsed=12

;0k,4j,8i,12ra, 16P_v, 20P_sz
IniStack:
<i,j,k
    i=^16  |j=^20
    i==0#.e|j<=0?#.e|D*i=0|#.1
.e: a=-1|stc|#.z
.1: malloc<(16)|a==0#.e|k=a
    a=j|c=8    |mul   c|r#.2
    malloc<(a) |a==0!#.3
.2:    free<(k)|#.e
.3: *i=k
    D*k+top=-1|D*k+size   =j
    D*k+arr= a|D*k+notUsed=0
    a^=a  ; => CF==0
.z:
>i,j,k
ret  8
etc etc

>> top,  size,  arr, notUsed
