Each of these entries is described in detail in the following paragraphs.
DdeDict
If you intend to use the element-by-element approach, this entry should contain the
file name of the Tandem DDE Gateway Dictionary created by the Bridge program on
the Tandem system and downloaded to the workstation. You do not need to specify
this option (or even download a Tandem DDE Gateway dictionary) if your application
uses only the binary-pass-through DDE Poke and DDE Request functions.
Note If you wish to use more than one Tandem DDE Gateway dictionary, configure them in the
[ApplicationDdeDicts] section of the Gateway Configuration File (usually TDMGW.INI).
Default
If a file name is not specified for the Tandem DDE Gateway dictionary file, then
the Tandem DDE Gateway looks for a DDEDICT.DIC file in the current directory
in effect when you start the Tandem DDE Gateway. If a DDEDICT.DIC file is not
found, you cannot use the element-by-element approach.
If you specify just a file name and extension (no directory), then the following
search path will be used:
1. The current directory in effect when you start the Tandem DDE Gateway.
2. The Windows directory (the one containing WIN.COM).
3. The Windows system directory (the one containing GDI.EXE).
4. The directory containing the executable file for the Tandem DDE Gateway
(TDMGW.EXE).
5. The directories listed in the DOS PATH environment variable.
Example
DdeDict=C:\TDMGW\DDEDICT.DIC
ElementCacheEntries
The Tandem DDE Gateway maintains a memory cache of data element names used in
element-by-element DDE Poke and DDE Request functions. This ensures good client
application performance when the same data element names are used repeatedly, for
example, when a client application does the same transaction type a number of times.
Increasing the cache size decreases workstation disk I/O, but increases workstation
memory usage.
Enter the number of data elements that can be stored in the Tandem DDE Gateway
dictionary cache. The range of values for ElementCacheEntries is 0 through 933.
