ERRORS PSAM/DAPDB Commands ERRORS
NAME
errors - display the positions of computational errors
SYNOPSIS
errors
DESCRIPTION
The errors command displays two types of error information.
Firstly, errors displays the contents of the user-defined
error recording variables, if any. This is known as the
User-Recorded Errors information. Secondly, errors indi-
cates whether there have been computational errors at any
time in the current program. This is known as the Any Errors
information.
In previous software releases errors displayed the mode and
location of the most recent unsuppressed computational
error. This information is no longer given. However, the
mode and location of the current computational error, if
any, can be displayed using message.
User-Recorded Errors
If error recording variables have been nominated,
their contents are displayed. Otherwise the mes-
sage No user-defined error recording variables is
displayed.
Error recording variables are displayed in the
same way that logical data of the corresponding
mode is displayed by the print command. Locations
in which errors have occurred correspond to .TRUE.
values.
Any Errors
The system maintains a logical scalar variable
which is initailly .FALSE. and is set .TRUE. fol-
lowing any run-time error (regardless of error
recording variables and error interruption masks).
Any Errors displays the value of this variable.
The "Any Errors" variable is cleared when the
FORTRAN-PLUS subroutine CLR_ERPT is called.
