Hi. I rewrote my last_patch51 to close bugs: 1) Ctrl-C/Ctrl-Z problem (my bugs in last patch) 2) arith bug - stack overflow (Manuel III bug): i=1; echo $(($i+1)) ash converted to arith(char *expr="1+1") l = strlen(expr)=3 stack=l/2 -> 1. But require minimum 2; This patch also included all work to close bug #1261 Ugh... --w vodz
