Error Messages and Anomalies
Chapter 9
9–6
BAD POSITION— This error occurs if you attempt to access a string
position that is beyond the declared length of the string when using CALL
66.
Example:
u10 STRING 100,9
u20 $(0)=“1234”
u30 $(1)=“56”
u40 PUSH 6 REM INVALID POSITION OF $(0)
u50 PUSH 1 REM $(1)
u60 PUSH 0 REM $(0)
u70 CALL 66 REM INSERT $(1) INTO $(0) @ POS 6
BAD POSITION error results because position 6 is outside of the declared
string.
EXTRA IGNORED — This error occurs when the resulting string cannot
hold all the characters when using CALL 61. Similar to insufficient string
size error. Extra characters are lost.
Input — An input statement requiring numeric data, received numeric data
followed by letters. The letters are ignored.
Example:
Input A
Entering 1.23AB causes this error message. The program continues to run.
INVALID MTOP ADDRESS ENTERED — This error occurs when you
select an invalid RAM location for a new MTOP value when using CALL
77.
PROGRAM NOT FOUND — This error occurs if a program number
higher than 255 is PUSHed when using CALL 71 or 72 or if the program is
not found.
