ARY_TRACE  -  Set the internal ARY_ system error-tracing flag

Description:
The routine sets an internal flag in the ARY_ system which enables or disables error-tracing messages. If this flag is set to .TRUE., then any error occurring within the ARY_ system will be accompanied by error messages indicating which internal routines have exited prematurely as a result. If the flag is set to .FALSE., this internal diagnostic information will not appear and only standard error messages will be produced.

Invocation:
CALL ARY_TRACE( NEWFLG, OLDFLG )

Arguments:
NEWFLG = LOGICAL (Given)
The new value to be set for the error-tracing flag.
OLDFLG = LOGICAL (Returned)
The previous value of the flag.

Notes:
  • By default, the error tracing flag is set to .FALSE., so no internal diagnostic information will be produced.
