Sorry but in the first message there is a big mistake. I didn't to write all
the program because it's quite long. So if somebody want to help me, I made
it right.

I wrote this function which works quite well except one thing, the second
time I use the function the program writes twice "Absolute (enter M) or
relative (enter A) displacement" without doing really something wrong but it
looks bad on the screen. The defect comes from the switch, and in fact it's
when the character is 'M' only (not with 'A') . Do you know if there any bug
with this "switch" or I did it wrong.

Thanks for helping me ...



int input_one_char(char CHAINEcharact[])

{
int test=0,check=0;
char charact;

do
   {
    printf("\r%s : ",CHAINEcharact);
    fflush(stdout);
    test=scanf("%c*[^\n]",&charact);
    charact=toupper(charact);
    switch (charact)
           {
            case 'A':
            case 'M':
                 check=1;
           };
    } while ((test!=1)||(check==0));

return charact;

int main()

......

Node->Type=input_one_char("Absolute (enter M) or relative (enter A)
displacement");
