This rang a bell with me
This is what I created
dcl-s Ix packed(7:0);
dcl-s Lengthoffield packed(7:0);

dcl-ds Rplcbadchards;
Completestring char(1000);
Completestringind char(1) dim(1000) pos(1);

Completestring = ChTxt;
Chtxt = Completestring;

dcl-proc Replacebadchar ;

Ix = 1;
Lengthoffield = %len(%trimr(Completestring));
dou Ix > Lengthoffield;
if Completestringind(Ix) < ' ';
Completestringind(Ix) = ' ';
Ix += 1;

end-proc ;
