Yes. But it is more involved.
Code:
/* you need a function dberror(int errcode, int line) that displays errors and exits */
void dberror(int errcode, int line)
{
       fprintf(stderr,"Error %d on line %d\n", errcode * -1, line);
       EXEC SQL
          ROLLBACK WORK RELEASE;
       exit(1);      
      
}
#define  ORACHK { if ( sqlca.sqlcode < 0) dberror(sqlca.sqlcode, __LINE__); }
typedef char CHAR21[21];
EXEC SQL BEGIN DECLARE SECTION;
     EXEC SQL TYPE CHAR21 IS STRING(21);
     CHAR21 name="";
     short ind=0;
EXEC SQL END DECLARE SECTION;

EXEC SQL
     SELECT 'Tom Jones' 
     INTO :name :ind
     FROM dual;
     ORACHK;

I added the ORACHK because you absolutely need to check return codes in Oracle.
What you do is up to you. This one is not friendly it just exits. You realize this won't compile; it is several different things blobbed together.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
