[bug-gawk] How awk keys are ordered?

[Peng Yu]

Hi, The following shows that awk hash keys are ordered numerically
whether the actual keys are actually numbers or strings. Does anyone
know when this assumption of ordering is true? Thanks.

~$ cat main1.awk
# vim: set noexpandtab tabstop=2:

BEGIN {
    for(i=1;i<=26;i++) {
        array[i]=1
    }
    for(i in array) {
        print i
    }
    for(i=1;i<=26;i++) {
        array["" i] =1
    }
    for(i in array) {
        print i
    }
}
~$ awk -f ./main1.awk
