I think this would be the prober way:
Include "MapBasic.def"
'...Declare Sub etc
Dim sTab As String,
aObj As Alias,
fMinX, fMinY, fMaxX, fMaxY As Float
oCur As Object
sTab = "ANYTABLENAME"
aObj = sTab + ".OBJ"
Set CoordSys Table sTab
Fetch First From sTab
Do Until EOT(sTab)
oCur = aObj
fMinX = ObjectGeography(oCur, OBJ_GEO_MINX)
fMinY = ObjectGeography(oCur, OBJ_GEO_MINY)
fMaxX = ObjectGeography(oCur, OBJ_GEO_MAXX)
fMaxY = ObjectGeography(oCur, OBJ_GEO_MAXY)
'**Here you do what you want to with these coordinates
Fetch Next From sTab
Loop

Subject: Re: [MI-L] Help with Object Functions
I did this also though this doesn't give any compile error , it gives error at
run time as argument is of invalid type.
Actually I am trying to visit all the objects ( which in my case are all
regions) of a perticular layer...so i am storing that layer's name in variable
tabname and than trying to read centroid , max and min points of its objects
using which I will zoom to them. But I am unable to understand why its not
working if i give the name (constLayer.obj) of layer instead of tabname (
variable) it works the way I want. Can u please explain ?
