There is a way.

// Normal split function, I just added a second delimiter
stock split(const strsrc[], strdest[][], delimiter1, delimiter2)
{
    new i, li;
    new aNum;
    new len;
    while(i <= strlen(strsrc))

        if((strsrc[i] == delimiter1 || strsrc[i] == delimiter2)|| i == strlen(strsrc))
        {
            len = strmid(strdest[aNum], strsrc, li, i, 128);
            strdest[aNum][len] = 0;
            li = i+1;
            aNum++;
        }
        i++;
    }
    return 1;

// Output:
