The new stuff is simpler !

ROTF,LMAO

Sorry Barbara,  Couldn' resist.  :-)

I think it's often used out of habit where newer string builtin functions
can handle the same task without bothering with arrays at all.

Anyway, to handle the function of MOVEA using EVAL:

C        MOVEA      arr1(n)     arr2(m)
C        MOVEA(P)   arr1(n)     arr2(m)
becomes

D src       s         65535a   based(pSrc)
D tgt       s         65535a   based(pTgt)
D srcLen    s            10i 0
D tgtLen    s            10i 0
 /free
        pSrc = %addr(arr1) + %size(arr1) * (n - 1)
        pTgt = %addr(arr2) + %size(arr2) * (m - 1)
        srcLen = %size(arr1) * (%elem(arr1) - n + 1)
        %subst(tgt : 1 : srcLen) = %subst(src : 1 : srcLen) // no padding

        tgtLen = %size(arr1) * (%elem(arr1) - n + 1)
        %subst(tgt : 1 : tgtLen) = %subst(tgt : 1 : srcLen) // padding
