Error handling

In this document, error handling in gtool5 library is described.

Error handling about parts of programs should be regulated definitely. Error means that input to the part of program is invalid, or expected operation can not be done, etc.

Procedures (procedures is generic name of subroutines and functions) provided to users by gtool5 library almost report error to invoker in the following two manner.

• When error occurs, the program display appropriate messages and aborts.
• If logical optional argument err is given, the argument *err* become .true. when error occurs. If err is abbreviated, the operation is same as above.

StoreError subroutine in dc_error module handle above all operations.

See Code references: dc_error for detail about interface of StoreError, etc.
