Arguments

   <variable>  
   
      The name of the global variable.

      Range: String  
      
   <value>  
   
      The value assigned to the variable.

      Range: Any Value  
      
   fme_attribute_name
   
      Indicates that the next argument is the name of an attribute that holds 
      the desired information.
      
      Range: N/A

   fme_get_mapping_file_keyword_<keyword>
   
      Returns the value of <keyword>.
      
      Range: N/A

   fme_get_mapping_file_flag_keyword_<keyword>
   
      Returns "yes" or "no" (all lowercase) depending on the return value of 
      STFConfig::fetchFlag(<keyword>).
   
      Range: N/A

   fme_get_mapping_file_upper_keyword_<keyword>
   
      Returns the value of <keyword>, converted to uppercase.
   
      Range: N/A

   fme_get_mapping_file_lower_keyword_<keyword>  
   
      Returns the value of <keyword>, converted to lowercase.
      
      Range: N/A

Configuration

   The @GlobalVariable function accepts two types of configuration lines:

   GlobalVariable <variable> <initialvalue> 
   
      This configuration indicates that the inital value of the specified global 
      variable be set to the given value. This will occur before the translation 
      begins.

   GlobalVariable MAX_TO_LOG <number>  
   
      This configuration configures the way the final state of all global 
      variables is reported in the log messages. The global variables will be 
      listed with their final values at the end of a translation.

      If this configuration line is not present, a maximum of 50 global 
      variables will be logged by default.

Description

   The @GlobalVariable function is used to set and read global variables. Global 
   variables are those that persist across all features during an FME 
   translation run.

   If this function is passed a single parameter, then the parameter is assumed 
   to be a global variable name and the function will simply return the value of 
   this variable. If the function is passed two parameters, then it will set the 
   global variable with the first parameter's name to have the value of the 
   second parameter. 

   A summary of the final values of all global variables used in the mapping 
   file is output to the log file at the end of the translation.

   If fme_attribute_name precedes either the variable or the value, the 
   variable/value is instead treated as the name of an attribute that holds the 
   information to use.

TO BE RESOLVED

   fme_get_mapping_file_ "backdoor" call arguments added to Syntax section 
   above, but not documented.
