Run-Time Messages
The following is a list of the system error messages you, or the users of your routines, may
receive should something go wrong retrieving, using, or storing assembly language routines. A
possible corrective action, or actions, is included in the discussion of the error.

ROM missing, or configuration error. To operate the 9835A/ B, all system
ROMs must be in place. In addition, to write assembly programs, the Assembly
Execution and the Assembly Development ROMs must also be installed. Per-
form the system test if the problem persists.
Memory overflow. You may have specified an ICOM which is too large for
your current available space. Some things to try: select a smaller ICOM size;
execute SCRATCH C (if no important data remain in common), delete mod-
ules and reduce the ICOM size; segment your BASIC prorams; segment your
assembly programs. The error may also be caused by trying to load modules
which are too large for the current ICOM region (either collectively or
individually) .
Improper argument in DECIMAL or OCTAL function. The OCTAL function
has a range from - 65535 to
+
65535. The DECIMAL function has a range
for its arguments of - 1777778 to
+
1777778.
Break Table overflow. A maximum of eight breaks can be established with the
IBREAK statements and be in effect at one time. If eight breaks are in effect,
then to allow other breaks to be established it is necessary to clear previous
breaks using the INORMAL statement.
:J.
E:; E Undefined BASIC label or subprogram name used in IBREAK statement.
When the IBREAK statement is executed, an undefined label or name is al-
lowed, but when the break actually occurs, the label or name must exist.
Attempt to write into protected memory; or, an attempt to execute an
instruction not in the ICOM region. This is the result of an attempt to branch
outside of permissible areas or to change the contents of memory outside of
the permissible areas. There is probably a difficulty in the logic of the program
which needs to be corrected. This error only occurs when the
@ill
key is being
used, an IBREAK DATA statement is in effect, or when using the ICHANGE
function.
