action.
• There is a problem in
the data.
Exemplar measures to be taken
• The program has deep nesting of a subroutine, "for" statement,
"next" statement, etc., with its nesting frequency exceeding 8 times.
Improvement of the program structure is required.
Exemplar measures to be taken
• This error is output if there is no nest starting statement such as
"for" at the point when "goto" statement refers to, or if a nest ending
statement such as "next" precedes the nest starting statement.
Check the structure of "for" statement and "next" statement and
make amendments as needed.
• There may be an overflow, underflow, or division by zero in four
arithmetic operations. Check the result of operations and amend
the operations as needed.
• This error is output if a non-existing parameter is referred to or a
setting is made beyond the setting range in "chg param" or "mon
param" instruction. Check the content of instruction and make
amendments as needed.
