Syntax |
DV [-R][-B][-O][-D][-H][-M][-P <prec>][-AL n][<var>] DV [-E]-Q <var> |
-R |
Force reloading of variable list (before performing variable display/search) |
-A |
Display in automatic format (default) |
-B |
Displays in binary format |
-O |
Displays in octal format |
-D |

-E |

-P <prec> |

-AL n |
Limiting internal arrays (structures) to maximum number n elements |
<var> |
Name of desired variable (*) |
If the command is executed non-interactively (e.g., in a batch file), it is mandatory to specify the variable; otherwise, if it is omitted, a variable selection window will be displayed, from those available on the current shell connection.
If more than one display format is specified, only the last one is used (if applicable): if none is specified, the default one is used, which depends on the type of the variable.
If no explicit group is specified for the variable, the one possibly set with VARDEF is used.
Both large arrays and the contents of complete structures (whether simple structures or multidimensional arrays of structures) can be displayed. In case the requested variable is very large, it is possible that the command will take a long time to complete the operation: possibly interrupt the command (or hotkey Ctrl+Break).
