asm6xx.dll

. It can be invoked from any

Windows program, provided that the user included the file called

in the Windows project.

The syntax of the call is:

extern int FAR PASCAL ASM_MAIN (LPSTR source_file, short *warn,short *err-
pass1,struct error_struct *,LPSTR include_list);

/* .... */

short i,w,pass1_error;

LPSTR source_file;

struct error_struct{

short pass;

/* pass where error was detected */

short type;

/* type of error (error, warning */

short error_msg;

/* error message number */

short file_number; /* file number in object file table */

long line_number;

/* line number in file where error occurred */

char info[MAXIDENTIFIER+1]; /* character string containing some */

/* information on the error */

};

struct error_struct error_list[MAX_ERRORS];

/* ..... */

i=ASM_MAIN(source_file,&w,&pass1_error,error_list,include_list);

Where:

source file is the assembly source file name.

is the number of warnings returned by the assembler.

pass1_error
