Hello Trey,

The min/max I was referring to, I'm not clear if it's the same as Pierre
intended though, was to place the min/max respectivly into individual point
objects which represent intersections or cross streets. If I understood him
correctly, he only wanted a label to appear at each end of the street.

As far as showing the high and low or min/max, I once used the same
expression that you suggest as well, till I relized it doesn't account for a
street which has a 0 value for one side or the other:

Fromleft=0 toleft=0
Fromright=2 toright=10

The min/max expression will label the range as 0-10, whereas the range is
2-10

The only way I could get around this was first, I added a "High" and "Low"
column to my streets table (as found in a Telco MSAG) export to mif,
changing the .mid to .csv I used Excel to run a minimum greater than zero -
maximum update on the high/low column, then brought backinto Mapinfo. But
this is done better with a Mapinfo Expression further down.

For Microsoft Excel:
Assuming:
A2=Street
B2=FromLeft
C2=ToLeft
D2=FromRight
E2=ToRight

=IF(B2=0,D2,(IF(D2=0,B2,(MIN(B2,D2)))))

Explanation:

If B2 equals 0, return D2 if not 0 return the following formula result:

If D2 equals 0, return B2, if not, return the minimum of the two numbers B2
and D2

Simon O'Keefe also provided an expression for Mapinfo SQL which would be far
more convienent:

update [street table set LOW =
left$(str$(minimum(FROMLEFT,FROMRIGHT)),99*int(FROMLEFT<>0 and
FROMRIGHT<>0)) + left$(str$(maximum(FROMLEFT,FROMRIGHT)),99*int(FROMLEFT=0
or FROMRIGHT=0))

getting the min/max is easy
here's a nice label I do

1) set label for dead center of the line
2) use "expression label"
3) minimum(fromleft,fromright)+"-"+maximum(toleft,toright)+chr$(10)+street
