Okay heres the offending code snippet:

there seems to be a loose CR character in there somewhere, the first loop
goes fine and then after the second it completely skips my first gets();  
btw.  fflush(stdin); works quite nicely on unix (sun), I guess its just
not completely ansi compliant.

void get_job(QUEUE *queue) 
{
	int count;
	ELEMENT job_buffer;
	for(count=0;count <MAX_QUEUE;count++)
	{
		fflush(stdin);
                printf("Enter job description: ");
                gets(job_buffer.job_des);
		printf("Enter job number: ");
                scanf("%d",&job_buffer.job_num);
		printf("Enter job priority: ");
		scanf("%d",&job_buffer.job_pri);
		insert(job_buffer,queue);
        }
}
