Line 50 CLOSEs the file.
Example program 2 — reading data using INPUT

20 INPUT# 1,D$
30 PRINT D$
40 IF ST=0 GOTO 20
50 CLOSE 1
Line 10 OPENSs the file for READ as TEST FILE.
Line 20 Reads a string from the tape into D$.
Line 30 Prints the value of D$ on the screen.
Line 40 Checks the status of the cassette. If the tape is OK then GOTO line 20.
Line 50 CLOSEs the file.
Example program 3 — reading data using GET
10 OPEN1,1,0,"TEST FILE"'
20 GET# 1,D$
30 PRINT D$
40 IF ST=0 GOTO 20
50 CLOSE1
Line 10 OPENSs the file for READ as TEST FILE.
Line 20 GETs a character into D$.
Line 30 Prints the character in variable D$ on the screen.
Line 40 Checks the status of the cassette. If the tape is OK then GOTO line 20.
