b. NETWORK 3 BASIC ERROR MESSAGES
The following is a description of error messages which may be encountered at a
Network 3 Student Station when a disk error or NBASIC error occurs.
AD File access denied
This error message occurs when a file protected by a password is called
without the password, when the wrong password is used, or when a
password is given and none exists (i.e., Password =" ").
AO File already open
This error message is generated when your program tries to open the same
file a second time,
without closing it between the two requests. It does not
occur when two Student Stations open the same file.
BM Bad file mode
This message occurs when you: 1) use random access statements to
manipulate sequential files; 2) use sequential statements to access random
files;
3) write to a file that is open for input; or 4) read a file open for
output.
BN Bad file number
File number refers to buffer number specified in FIELD, OPEN and CLOSE
statements. This error occurs when the program attempts to .access a file
with an invalid buffer number.
DF Disk full
The space allotted for program and data storage on the diskette is full. If
this error message appears while saving a program to disk, the program was
probably not saved in its entirety.
DS Direct statement in file
30
When a LOAD"filename" command is entered, the · system requires that the
file be a BASIC program (i.e., a file in which every line begins with a line
number).
If it is not a BASIC program, then a file cannot be loaded. This
happens if the file is data (not a program), or if there was a write error when
the file was saved or a read error during loading. A flawed track on a
diskette could also cause this message. Possible solutions are to COPY the
file to another disk and try again, BACKUP the disk, or read the program
in line by line by another program, correct the bad line number, and save it
on another disk.
