$LFIX

$LFIX converts an unsigned INT value to a FIXED(fpoint ) value.

int-expression

is an unsigned INT expression.

fpoint

is a value in the range -19 through +19 that specifies the position of the implied

decimal point in the result. A positive fpoint specifies the number of decimal

places to the right of the decimal. A negative fpoint specifies the number of

integer places to the left of the decimal point.

$LFIX places the INT value in the low-order (least significant) word of the

quadrupleword and sets the three high-order (most significant) words to 0.

Example 15-50. $LEN Routine

INT s_len;

STRUCT .s[0:99];

BEGIN

INT(32) array[0:2];

END;

s_len := $LEN (s); ! Return 12

Example 15-51. $LEN Routine

INT array_length;

INT(32) array[0:2];

array_length := $LEN (array) * $OCCURS (array);

! Return 12, the length of the entire array in bytes
