Compiler weirdness

gerwynd

Anyone, please look at the below code. Its a fragment of a bigger project which I have studied and studied but find no reason for the syntax error indicated below.

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;

}

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.
