MDL application is written using C Language and we have to execute MDL Application by calling "mdl load <application name>.ma " within the PHP code.
" <application name>.ma " is the executable file.
I saw an example as :
<a href=\"app:mdl load locatedocid.ma \">
I don't know what that "app:" denotes.
But when I used the code as similar, execution of PHP program gets stopped when it reaches the line of referencing MDL Application.
