Syntax

── ? ── DENY ──────────────────────────────────────────────────────────%

Explanation

The ?DENY command denies program requests for I/O from the station. An end-of-file notice is sent to all programs that have files pending, postponed, or open at the station.

The ?END and ?DENY commands differ in that ?END causes end-of-file action only on the input or I/O file. ?DENY also acts on output files.

Example

L DON1
1100 BEGIN
1200 STRING A;
1300 INTEGER I;
1400 FILE DCOM(KIND=REMOTE,MYUSE=OUT);
1500 A:= "HELLO THERE";
1600 DO BEGIN
1700 WRITE (DCOM,20,A);
1800 WAIT ((3));
1900 I:=I+1;
2000 END
2100 UNTIL I EQL 3
