SX/B Error Codes

The SX/B compiler can trap several programming errors before generating the assembly output that is passed to the SASM assembler. The list below gives a description of the errors and guidance for correction.

Error 1 INVALID VARIABLE NAME

You have used a variable name that is an SX/B or SASM reserved word.

Error 2 DUPLICATE VARIABLE NAME

You have tried to allocate the same variable name more than once.

Error 3 VARIABLE EXCEEDS AVAILABLE RAM

You have declared too many variables or the array is too large.

Error 4 CONSTANT EXPECTED

The bit field value must be a constant.

Error 5 BYTE PARAMETER EXPECTED

Many commands work only with BYTE parameters.

Error 6 INVALID UNARY OPERATOR

You used a unary operator other than – (negate) or ~ (bitwise NOT).

Error 7 INVALID REGISTER OPERATION

Some SX registers are write-only, hence assignment is the only valid operation.

Error 8 INVALID PARAMETER

You have used a parameter that is not valid.

Error 9 SYNTAX ERROR

Command syntax not followed.

Error 10 INVALID NUMBER OF PARAMETERS

You have given too few or too many parameters for the command.

Error 11 BYTE VARIABLE EXPECTED

You have used a non-byte variable where a byte was expected.

Error 12 NOT A FOR CONTROL VARIABLE

You have used NEXT with a variable what was not used in a previous FOR instruction.

Error 13 BIT VARIABLE EXPECTED

You have used a non-bit variable where a bit variable is required.

Error 14 BAUDRATE IS TOO LOW

Baudrates are limited by the FREQ setting. Use a higher baudrate or lower clock frequency.

Error 15 BAUDRATE IS TOO HIGH

Baudrates are limited by the FREQ setting. Use a lower baudrate or higher clock frequency.

Error 16 UNKNOWN COMMAND

Instruction used is not supported or is misspelled, or you have misspelled a variable name.

Error 17 COMMA EXPECTED

In most cases you must separate parameters with a comma.

Error 18 EXPECTED A VALUE BETWEEN 0 AND 7

Bit operations require a value from 0 to 7.

Error 19 BIT IS NOT A HARDWARE PIN

Some commands operate only on hardware pins.

Error 20 BIT CONSTANT EXPECTED

Expected 0 or 1.

Error 21 INTERRUPT MUST BE USED BEFORE PROGRAM

Interrupt routine must be placed before the PROGRAM directive.

Error 22 FOR WITHOUT NEXT

You have created a FOR loop without a corresponding NEXT, or you have misspelled the FOR control variable name.

Error 23 NEXT WITHOUT FOR

You have used NEXT without a corresponding FOR, or you have misspelled the NEXT variable name.

Error 24 UNKNOWN VARIABLE NAME

You have attempted to use an undeclared variable, or misspelled a variable name.

Error 25 TOO MANY SUBS DEFINED

A maximum of 127 subroutines may be defined in any one program.

Error 26 ELSE OR ENDIF WITHOUT IF

You have used ELSE or ENDIF without a corresponding IF.

Error 27 VARIABLE NOT IN CURRENT BANK

The variable used is not accessible from the current bank.

Error 28 MUST BE A GLOBAL VARIABLE

Some commands (BANK) require a variable that is located in the global RAM area. Place global variables at the beginning of the declaration section.

Error 29 LOOP WITHOUT DO

You have used LOOP without a corresponding DO.

Error 30 EXIT NOT IN FOR...NEXT OR DO...LOOP

The EXIT command must be used within a FOR...NEXT or a DO...LOOP construct.

Error 31 FREQUENCY DIFFERENT FROM DEVICE SETTING

The clock speed you have specified with FREQ does not match the clock speed specified on the DEVICE> line. This only occurs when the device line specifies one of the internal clock speeds (OSC4MHZ, OSC1MHZ, OSC128KHZ, or OSC32KHZ)

Error 32 NOT ALLOWED ON THIS DEVICE

Some commands (like TIMER1) only apply to the SX48/52 devices. If you attempt to use these commands on the SX28 you will receive this error.

Error 33 NO PROGRAM DIRECTIVE USED

All SX/B programs must use the PROGRAM Label directive so that the SX knows where to start program execution.
