||List command aliases.
|alias name text
||Create a new alias name with the replacement value text.
The replacement text is not limited to a single word but may contain spaces.
|assign var = expr
||Assign the value of expr to variable var.
The variable can be scalar, an array (including an array section),
a scalar component, or an element of an array component, but cannot be
of derived type.
The value must be a scalar expression (see “Expressions” for more
||Continue execution from where it was stopped (either by a breakpoint or an
||Delete breakpoint number n.
||Delete all breakpoints.
||List the expressions to be displayed after each breakpoint is reached.
||Add expr to the list of expressions to display after each breakpoint.
Expr may also be an array section.
||Display all local variables and their values.
||Move the focus down (i.e. to the procedure called by the current procedure).
If n is present, move down n levels.
||Display a brief help message on the specified topic, or on using
||List the history command buffer.
Old commands can be executed with:
- repeat last command,
- ! n
- repeat command n in the history buffer, and
- ! -n
- repeat the
||Set the size of the history command buffer to n commands.
The default size of the history command buffer is 20.
||This is actually a suffix to the breakpoint (‘stop’)
commands not an independent command.
It prevents the triggering of the breakpoint until the expression expr
(a scalar expression) is .TRUE. (or non-zero).
||Display the next 10 lines of the program, display line line1 of the
current file or display lines line1 to line2 of the current file.
||Execute the next n lines (default 1) of the current (or parent) procedure.
Any procedure reference in these lines will be executed in its entirety unless
a breakpoint is contained therein.
|print expr [,expr]...
||Display the value of expr,
which can be a scalar expression, array section, derived type
component,or a variable of any data type. Several expressions may be
given separated by commas.
||Exit from dbx90, immediately terminating any program being debugged.
||Pass dbx-command directly to “dbx”.
This is not recommended for normal use.
||Begin a new execution of the program, passing command-line to it (if
present) or the command-line from the previous run or rerun command if
||Begin a new execution of the program, passing command-line
to it (if present) or blank command line if not.
||Display the current procedure name or set the focus to the specified procedure
||List the breakpoints which are currently set.
||Execute the next n lines (default 1) of the program, counting lines in
referenced procedures (i.e. step into procedure references).
||Set a breakpoint which triggers when variable name is accessed.
Note that name cannot be ‘at’ or ‘in’.
This command is not available on Solaris or HP-UX.
|stop at lineno
||Set a breakpoint at line lineno of the file containing the current
|stop in name
||Set a breakpoint at the beginning of procedure name.
Note that this breakpoint occurs at the beginning of procedure initialisation,
not at the first executable statement.
If there is no procedure called ‘MAIN’, the main program can be
specified using that name.
||Remove expr from the “display” list.
||Move the focus up (i.e. to the caller of the current procedure).
If n is present, move up n levels.
||Describe how name would be explicitly declared.
||Display the stack of active procedures with their dummy argument names.
||Display the fully qualified form of name
which can be used for access from another scope.
