SCAN |
This command is used to search for a string of characters within an object, with the option to replace the string with another string.
The object may be a single object, all objects beginning with a specified setting, or all objects within a library. The scan may also be restricted to a specific object type.
Important:
The source work area is used by the
SCAN command. Therefore, a SAVE or
STOW command
should be issued before using the SCAN command.
Note:
This command is not executable in batch mode.
This document covers the following topics:
Any objects except maps, DDMs and data areas can be modified using the scan utility. You can also use the full screen editor to modify other lines than scanned lines. When the object is modified, save it and close the editor. You can then continue scan processing.
When you issue the SCAN command, a window is
displayed where you can specify the following:
| Field | Explanation | |
|---|---|---|
| Scan value | The value to be searched for. | |
| Replace value | The value which is to replace the scan value. | |
| Delete value | Will cause the scan value to be deleted (Y/N). | |
| Object name | The object(s) to be scanned: | |
| blank | All objects. | |
| * | ||
| name* | All objects whose names begin with name. | |
| Object type | The type(s) of object to be scanned: | |
| P | Programs | |
| C | Copycodes | |
| N | Subprograms | |
| S | Subroutines | |
| H | Helproutines | |
| M | Maps | |
| G | Global data areas | |
| L | Local data areas | |
| A | Parameter data areas | |
| T | Texts | |
| 4 | Classes | |
| * | All types | |
| Absolute scan | Y | Will result in an absolute scan. |
| N | If absolute scan is set to "N", the scan value must be separated by a blank or specific character. | |
| Library | The ID of the library to be scanned. Default is the current library. | |
| Case sensitive | N | The search will be for the scan value regardless whether it occurs in upper case, lower case, or a mixture of both. |
| Y | The search will be for the scan value exactly as you specify it. | |
Make the desired specifications and press ENTER. A window appears displaying the lines containing the searched for scan value.

Any desired subcommand can be entered in the above window. To enter the command mode, place the cursor in the Commands line and press ENTER.
Then you can select one of the following commands:
| Command | Function |
|---|---|
| Edit | Edit object.
Note: |
| List | List object as it currently appears in the source work area. |
| Ignore | Ignore the object currently being scanned, do not save any modifications, and continue with next object. |
| Quit | Terminate scan processing. |
A subcommand can also be invoked by entering its first character.
To deactivate command mode, press ESC.
If the Replace option is used and/or an object is updated in the scan utility, the object will always be saved unless or is specified before the next object is scanned.
Lines containing PASSWORD=, PASSW=,
CIPHER=, or CIPH= will be ignored by the
SCAN command.
The line length of the source object in the scan utility is limited to 72.
If the replace value causes a line to exceed 80 characters, the line will be split automatically.
In order to use SCAN in a Natural Security
environment, the system commands LIST,
EDIT, and
READ must be
allowed in the current library's security profile. If the Replace option is to
be used, the system command SAVE must also be
allowed.
Under Natural Security, the use of the SCAN
command may be disallowed in some libraries.
