• DO instruction contains a negative number or 1000 as the
initial and final values.
• When specifying a negative line number in the GTO or GTS
instruction.
• Running a program that exceeds capacity.
• Enter a program that exceeds capacity.
• Specifying memory that does not exist in the indirect
designation of memory.
• Specify a step that exceeds the capacity with the cursor up
operation.
• If the following line is not defined in the skip operation of the
• If the REC, LOD & CHK instructions at the time of program
instruction execution do not define the next line of those
written lines.
• When executing the CHK instruction, if an error occurs due to
the check operation.
• If you execute the LOD instruction on a magnetic care where
nothing is recorded (first card only).
• LOD instruction, CHK for magnetic cards whose contents are
broken due to external magnetic fields.
• If you execute a LOD, CHK or REC instruction while the cover is
attached to the magnetic card or on the head of the card reader
• If the card operation is inappropriate.
• If you try to enter a program > 100 lines.
• If you try to execute > 100 lines at the time of program
execution.
• If you try to specify a program that exceeds 100 lines by cursor
The error message format is typical of Fortran based computers. If
an error is detected the program halts at the line number that
generated the error and displays a code explaining the error.
