  Remove the semicolon after the stack variable declarations

  DEFINE_TYPE 
  STRUCTURE lightingDevices
  {
      INTEGER ID
      CHAR Name[30]
  }
  
  DEFINE_CONSTANT
  VOLATILE INTEGER nMaxLightingDimmers = 30;
  VOLATILE INTEGER DIMMER_LAMP_1  = 1;
  VOLATILE INTEGER DIMMER_LAMP_2  = 2;
  VOLATILE INTEGER DIMMER_LAMP_3  = 3;
  VOLATILE INTEGER DIMMER_LAMP_4  = 4;
  VOLATILE INTEGER DIMMER_LAMP_5  = 5;
  
  DEFINE_VARIABLE
  lightingDevices TDIMMERS[nMaxLightingDimmers]
  
  DEFINE_FUNCTION INITIALIZE_STRUCTURES()
  {
      STACK_VAR INTEGER i
      STACK_VAR INTEGER i2
  
      TDIMMERS[1].ID = DIMMER_LAMP_1;
      TDIMMERS[2].ID = DIMMER_LAMP_2;  // <<< SYNTAX ERROR INDICATED FOR THIS LINE HERE ??
      TDIMMERS[3].ID = DIMMER_LAMP_3;
      TDIMMERS[4].ID = DIMMER_LAMP_4;
      TDIMMERS[5].ID = DIMMER_LAMP_5;
  }

  Syntax errors are usually pretty hard to track down because the compiler usually flags the wrong line. I'd try looking somewhere above that function to see if anything looks unterminated. I tried duplicating your code and this file compiles without error:

  PROGRAM_NAME='Compiler Main'
  
  DEFINE_CONSTANT
  
  DIMMER_LAMP_1 = 1
  DIMMER_LAMP_2 = 2
  DIMMER_LAMP_3 = 3
  DIMMER_LAMP_4 = 4
  DIMMER_LAMP_5 = 5
  
  DEFINE_TYPE
  
  STRUCTURE TDIMMER
  {
      INTEGER ID
  }
  
  DEFINE_VARIABLE
  
  VOLATILE TDIMMER TDIMMERS[5]
  
  DEFINE_FUNCTION InitializeStructures ()
  {
      STACK_VAR INTEGER i
      STACK_VAR INTEGER i2
  
      TDIMMERS[1].ID = DIMMER_LAMP_1
      TDIMMERS[2].ID = DIMMER_LAMP_2
      TDIMMERS[3].ID = DIMMER_LAMP_3
      TDIMMERS[4].ID = DIMMER_LAMP_4
      TDIMMERS[5].ID = DIMMER_LAMP_5
  }
  
  DEFINE_START
  
  InitializeStructures()

  Semicolons are allowed at function stack_vars....

  define_function CHAR[20] CreateFaderString(integer nModuleID, integer nParamType, integer nParam1, integer nParam2)
  {
      stack_var char sFinalString[20];    // der finale String mit Anfangsbytes, checksumme und Daten 
      stack_var integer nChksumValue;     // Summe der 2 Startbytes und der Databytes
      stack_var char sChkSumBytes[2];     // Summe auf 2 Bytes umgerechnet
      stack_var char sData[8];                    // Datenbytes
      stack_var integer nX;                           // Zähler FOR() Schleife
  
      // Die Control Daten zusamensetzen, gleich ins passende Format
      sData = "IntegerToBytes(nModuleID,1), IntegerToBytes(nParamType,1), IntegerToBytes(nParam1,1), IntegerToBytes(nParam2,1)";
  
  //further stuff to follow
  }
  

  works fine, just wrote this an hour ago....

  Also tried again with the original code, compiles well for me:

  define_type
  struct dimmers
  {
  integer id
  }
  
  define_constant
  integer DIMMER_LAMP_1 = 1;
  integer DIMMER_LAMP_2 = 2;
  integer DIMMER_LAMP_3 = 3;
  integer DIMMER_LAMP_4 = 4;
  integer DIMMER_5 = 5;
  
  define_variable
  dimmers TDIMMERS[5];
  
  
  DEFINE_FUNCTION INITIALIZE_STRUCTURES()
  {
  STACK_VAR INTEGER i;
  STACK_VAR INTEGER i2;
  
  i2 = 0; //  <<<<<<<<<< IF I REMOVE OR COMMENT THIS POINTLESS LINE OUT, I GET A SYNTAX ERROR ??
  
  TDIMMERS[1].ID = DIMMER_LAMP_1;
  TDIMMERS[2].ID = DIMMER_LAMP_2;  // <<< SYNTAX ERROR INDICATED FOR THIS LINE HERE ??
  TDIMMERS[3].ID = DIMMER_LAMP_3;
  TDIMMERS[4].ID = DIMMER_LAMP_4;
  TDIMMERS[5].ID = DIMMER_5;
  }
  

  By whatever reason, sometimes invisible, not allowed characters find the way into the sourcecode file, and the compiler gets in trouble with that, reporting a syntax error that "visibly doesn't exist". Finding them is hard, sometimes only possible by a hex editor....

  I also can remember that there are also some combinations of code elements that the compiler interprets as syntax errors, though by language are ok.
