 #!Rall989 Getting Started Writing a Module #!N #!EC #!N #!N To 
build a module, you must: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N 
#!I30 #!N 1. Define the module's function and its interface (i.e., 
its inputs and outputs). #!N #!I30 #!N 2. Create a  #!F-adobe-times-medium-i-normal--18*   
module description file #!EF containing this information. #!N #!I30 #!N 3. 
Write the module. #!N #!I30 #!N 4. Compile and link the 
module. #!N #!I0 #!N #!EF #!N #!N #!N Once you have 
completed these four steps, you can run a version of Data 
Explorer that incorporates the module. #!N #!N The Module Builder is 
a point-and-click interface that facilitates much of this work by creating 
the files necessary for a module: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N 
#!N #!I30 #!N o a module description file #!N #!I30 #!N 
o a C-code framework (or template) file #!N #!I30 #!N o 
a makefile. #!N #!I0 #!N #!EF #!N All you need do 
is add your own application code to the framework file. (See 
 #!Lmblder,dxall1003 h Module Builder  #!EL  .) #!N #!N A module can be added to Data 
Explorer in one of three forms:  #!F-adobe-times-medium-i-normal--18*   inboard #!EF ,  #!F-adobe-times-medium-i-normal--18*   
outboard #!EF , or  #!F-adobe-times-medium-i-normal--18*   runtime-loadable #!EF . An inboard module 
is linked directly into a new Data Explorer executive. An outboard 
module is a separate executable linked to the Data Explorer routine 
library and controlled by the executive. It can later be compiled 
and linked as an inboard module for greater efficiency. A runtime-loadable 
module can be loaded when Data Explorer is started or while 
it is running. It is more portable than the inboard module 
version of the same function and more efficient than the outboard 
version. See  #!Lmodsior,dxall1049 h Inboard, Outboard, and Runtime-loadable Modules  #!EL  . #!N #!N #!N  #!F-adobe-times-medium-i-normal--18*   Next Topic #!EF
