[THE_KNOWN]

i dont know but maybe you could use:

pawn Код:

stock splitstring(actualstring,&split1[],&split2[])
{
    if(sizeof(actualstring) > 100)
    {
        new rlen = sizeof(actualstring) - 100, str[rlen];
        format(split1,100,"%s",actualstring);
        for(new i;i<rlen;i++)
        {
            split2[i]=actualstring[99+i];
        }
    }
    return 1;
}

untested.

split1 string will contain first 100 chars and the split2 string will be fed with chars starting from 100th from actualstring
