Using the ^%GSIZE Routine

The ^%GSIZE routine enables you to determine the size of one or more globals.

Basics

To use this routine:

Start an ObjectScript shell.
Start the routine:
```
 do ^%GSIZE
```
The first prompt lets you specify the database to look at. The prompt refers to the directory that contains the database file:
```
Directory name: c:\intersystems\iris211\mgr\enslib\ =>
```
The default is the globals database used by the namespace that you are currently in. You can either press Enter to accept this default, or type a full directory name and then press Enter.
The next prompt is as follows:
```
All Globals? No =>
```
If you want information on all globals, enter Y (case-insensitive). Otherwise press Enter.

Note:

If you request information on all globals, that includes all the internal, undocumented globals as well as your own globals. Some of these are quite large.
If you did not enter Y in the previous step, the next prompt looks like the following, which is asking for a global name:
```
Global ^
```
Type the global name, without the leading caret and press Enter.
Repeat as necessary. When you are done entering global names, press Enter again. Then the routine displays a message indicating how many globals you have selected:
```
All Globals? No => No
Global ^IRIS.Msg
Global ^Ens.Config
Global ^
2 globals selected from 64 available globals.
```
The next prompt asks whether to provide a full report on the globals:
```
Show details?? No =>
```
If you want full information, enter Y (case-insensitive). Otherwise press Enter
Press Enter for the next two prompts, which let you specify where to write the output:
```
Device:
```
and
```
Right margin: 80 =>
```

The routine then displays output like the following (using N for the Show details prompt):

           Global Size Display of c:\intersystems\iris211\mgr\enslib\
                              2:44 PM  Aug 15 2024
 
  Ens.Config       1    IRIS.Msg     906
 
      TOTAL:     907

When using Y for the Show details prompt, the report looks like this instead:

           Global Size Display of c:\intersystems\iris211\mgr\enslib\
                              2:44 PM  Aug 15 2024
 
  Ens.Config       1    IRIS.Msg     906
 
      TOTAL:     907
directory: c:\intersystems\iris211\mgr\enslib\
Page: 1                           GLOBAL SIZE                        15 Aug xxxx

      --------    --------  ---------------  -------   -------
      Ens.Config         1               36      0 %         0
      IRIS.Msg         906        5,550,960     75 %       746
 
 
      TOTAL         Blocks       Bytes Used  Packing   Contig.
      --------    --------  ---------------  -------   -------
                       907        5,550,996     75 %       746
                                        <RETURN> to continue or '^' to STOP:
