It should be noted that there is not a one-to-one correspondence between
format escapes and format instructions; many instructions have side
effects. Instructions prefixed with
LV_DAT Load value from \fIdat\fR array into \fInum\fR register (see note)
LV_STRLEN Set \fInum\fR to the length of \fIstr\fR
LV_PLUS_L Add value to \fInum\fR register
-LV_MINUS_L Substract value from \fInum\fR register
+LV_MINUS_L Subtract value from \fInum\fR register
LV_DIVIDE_L Divide \fInum\fR register by value
LV_MODULO_L \fInum\fR modulo value
LV_CHAR_LEFT Store remaining number of printable chars in \fInum\fR
