Appendix E
Creating Libraries for Use with INTOUCH

BTo create libraries for use with INTOUCH, you will need to follow these steps:

Write the source code using an editor. The source code can be B in BASIC, FORTRAN or any other VMS provided language that F supports the common calling interface. Here is an example of a BASIC routine:
```
'        10  SUB MULT(IN1%, IN2%, OUT%)             OUT% = IN1% * IN2%             END SUB 
```
F
This file has only one subprogram. Your file can contain any number of subprograms. U
Compile the source code with the appropriate compiler. For instance, I the above BASIC routine would have to be compiled with the BASIC compiler:
```
        $ BASIC MULT 
```
Create an options file.
- Use an editor to create an options file. Give the optionsE file a file extension of ".OPT". Enter the option UNIVERSAL E to specify the modules (subprograms and functions) contained in your routine.
```
-            UNIVERSAL = module [, module...] 
```
- If your routine contains more than one module, separateB multiple module names with commas. The routine described # above has only one module:
```
            UNIVERSAL = MULT 
```
Link the library.
```
9            LINK/SHARE routine_name,options_file/OPTIONS 
```
- For the routine above, if your options file is called' MULT.OPT, the link command is:
```
+            $ LINK/SHARE MULT,MULT/OPTIONS 
```
BYou have now created the shareable image MULT.EXE, containing the Aroutine MULT. You can now use this routine from within INTOUCH.
@To use the routine, first name the library with a LIBRARYJstatement, supplying the complete file specification INCLUDING DEVICE AND DIRECTORY. 3Then, execute the routine with the CALL statement.
```
2        10  library "DUA1:[STEVE.MODULE]MULT.EXE" '            call mult(8%, 9%, answer%) ,            print 'The answer is '; answer% 
```
FYou can have any number of LIBRARY statements in a program. When you Kcall a routine, each library specified is checked in turn for the routine.

F.1 Supported Database Engines

GMultiple database engines (record management systems) can be used with BINTOUCH. The following database engines are currently supported:
- RMS
- Rdb
- DBMS
- USERBASE
- POISE
- FASTFILE
- S1032
- INGRES
- dBASE III
- ADABAS
- ORACLE
FThe SETUP routine tells INTOUCH where data files are located and what Krecord management systems are used. Once you have defined your structures Fusing SETUP, you can use INTOUCH's structure statements to manipulate the data.
GFor detailed information on INTOUCH interfaces to the various database engines, you can refer to:
- the INTOUCH 4GL - Interfaces to Database Engines manual. V
- Chapter 16, Creating Structures, Field Definitions with SETUP, in this manual.
