hello

>L1:={4, 6, 9, 3};
>FOREACH L1 AS it if(it MOD 2 == 0) it=it-1; END;
>// now L1 is { 3, 5, 9, 3 }

L1-((L1 MOD 2)==0) does that

L1 MOD 2 does a modulo 2 of each element of L1
the ==0 will return a list of 0 and 1, with 1 for every element of L1 that is 0
and the final - removes that 1 in cases of equality mod 0 from L1
