Chapter 9 - Generating Procedural Languages

9.1 - C top

Code Example 28 - Generating C
Generate `set` and `get` "methods" for two "members" of a C "class".

Source code - File "language/c_getset"

    1      @ dash &
    2      @ language/c/get_set(int,Quantity,quantity)
    3      @ language/c/get_set(double,Percentage,percentage)

Output of "/opt/somusar/bin/tefigel language/c_getset"

    1      static int quantity;
    2      
    3      int getQuantity() {
    4          return quantity;
    5      }
    6      
    7      void setQuantity( int v_quantity ) {
    8          quantity = v_quantity;
    9      }
   10      
   11      static double percentage;
   12      
   13      double getPercentage() {
   14          return percentage;
   15      }
   16      
   17      void setPercentage( double v_percentage ) {
   18          percentage = v_percentage;
   19      }
   20

C get/set subroutine - File `"language/c/get_set"`
1 @ interface(TYPE,IdId,idId) 2 static TYPE idId; 3 4 TYPE get&IdId() { 5 return idId; 6 } 7 8 void set&IdId( TYPE v_&idId ) { 9 idId = v_&idId; 10 } 11

9.2 - Visual Basic® top

Code Example 29 - Generating Visual Basic®
Visual Basic® fragment containing a comment and a message to be printed out in a message box.

Source code - File "language/vbasic"

    1      @ set msg=Hello!
    2      ' Print out a message
    3      MsgBox "The message is: msg"
    4

Output of "/opt/somusar/bin/tefigel language/vbasic"

    1      ' Print out a message
    2      MsgBox "The message is: Hello!"
    3

9.3 - COBOL top

Code Example 30 - Generating COBOL
Small fragment of PROCEDURE DIVISION that prints out a message.

Source code - File "language/cobol"

    1      @ set program_name=PROGRAM 0
    2      @ set hello_message=Hello, world!
    3            ****************************************************************
    4             PROCEDURE DIVISION.
    5             P0.
    6            ** print a message
    7                 DISPLAY 'program_name: hello_message'.
    8

Output of "/opt/somusar/bin/tefigel language/cobol"

    1            ****************************************************************
    2             PROCEDURE DIVISION.
    3             P0.
    4            ** print a message
    5                 DISPLAY 'PROGRAM 0: Hello, world!'.
    6

9.4 - RPG top

Code Example 31 - Generating RPG
RPG fragment containing a comment and a message to be printed out.

Source code - File "language/RPG"

    1      @ set msg=Unknown Code
    2       * Display an error message
    3      Dtext               m                       msgtext('msg')

Output of "/opt/somusar/bin/tefigel language/RPG"

    1       * Display an error message
    2      Dtext               m                       msgtext('Unknown Code')
