James,

character files?  

I'm afraid you caught me out. I was planning to the stdin/stdout work today,
I thought it would be easy.
Just do this, right ?

    FILE *fptr;

    if (strcmp(filename,"stdin") == 0 ) {
        fptr = stdin;
    } else {
        fptr = fopen(filename, "r");
    }

Ah well....

I'll take a look at bcp_moretext(). It should be possible.

Bill
