Hi,

First, thanks to those who replied to my last buffer question.!!
Now, here is my code..

void
PushBackChar(char aChar)
{
    unsigned int       temp2;
    unsigned int far  *tail = (unsigned int far *)(0x0040L << 16 |
                                                   0x001CL);
    unsigned int far  *head = (unsigned int far *)(0x0040L << 16 |
                                                   0x001AL);

    temp2 = *tail;
/* let's go to next box, see where we are.!*/
    temp2 += 2;

    if (temp2 <= 0x3E)
        goto still_got_space;
    else
    {   /* go back to start*/
        temp2 = 0x1E;
        temp2 += 2;
    }

still_got_space:
    if ((*head) == temp2)
        goto cant_push;
    else                        /* don't care about ext. keys */
    *((int far *)(0x0040L << 16 | (long)(temp2 - 2))) =
                                              (unsigned)aChar;

                                /* update tail */
    *((unsigned far *)(0x0040L << 16 | 0x001CL)) = temp2;

cant_push:;
 /* trash */

};



this code works just fine(Well.! not always!!..), but there is a
problem. Sometimes, DOS shell reads whatever I pushed recursively
'till I do Ctrl-C (I am using this to push some strings back to DOS
shell from a tsr). Does anybody know/see what the problem is?
 Thanks in advance.
