Just a quick look at your code, you have not declared your globals before DIMming.
As the help file shows:

Code:

#COMPILE EXE

GLOBAL Caption AS ASCIIZ * 255

 

FUNCTION PBMAIN() AS LONG

  DIM Msg AS ASCIIZ * 255

  CALL SetVars

  IF Caption = "GLOBAL test" then Msg = "Success!"

END FUNCTION

 

SUB SetVars()

  Caption = "GLOBAL test"

END SUB

If you run example code, you will see that an outside global definition has no effect.

But I normally do provide these def's.

I put this example together to provide code in demonstrating the Mapfile exchange problem.

Thank you for looking.

After changing these two lines from this:

Code:

 ARRAY SCAN atZoo(), COLLATE UCASE, FROM 1 TO LEN(pZoo), = UCASE$(pZoo), TO Index
ARRAY SCAN atAnimalName(), COLLATE UCASE, FROM 1 TO LEN(pAnimalName), = UCASE$(pAnimalName), TO Index2

to this:

Code:

ARRAY SCAN atZoo(), FROM 1 TO LEN(pZoo), COLLATE UCASE,=UCASE$(pZoo),  TO Index 
ARRAY SCAN atAnimalName(), FROM 1 TO LEN(pAnimalName), COLLATE UCASE, = UCASE$(pAnimalName), TO Index2

I started getting some different reponses. But there are still some things that aren't right I think, but you would know better than I.
I would have thought that you would get a syntax error.

>I would have thought that you would get a syntax error

#DIM ALL is your friend and will give you that undefined variable error.

I still think this should have been the default, requiring the programmer to explicitly code...

Code:

#DIM NONE  '  I want to suffer.

Rodney:

COLLATE UCASE position change

No effect

Michael:

Under PBCC 5

#Dim ALL
#Dim None

The compiler returns no errors either way

Here is the code reformated

So both PBCC 4 and 5 will accept it.

Globals predefined

No forward references

Code:

'
'   Mapfile example of my problem
'
'   I can not read the data exchanged pass the first Index of the Arrayed UDT
'
'   As can be seen by the code execution the aZooKeeper() array of ZooType has the data
'   but the Mapfile only delivers data from Zoo Index 1
'
'
'   Change the %Send=-1 to compile the send file
'              %Recv=-1 to compile the Recv file
'
'           Please don't do both I'm not check for that right now
'
'       The code is set for %Send=-1 now
'
'   ********************************************************************
'
'    The Send will add a new zoo entry on each [return]
'
'    5 (Index2 1-5) for Index=1 for Boston
'    5 (Index2 1-5) for Index=2 For Omaha
'
'    You can see the entry value after each action
'
'    It will then enter "Zoo Index and Animal Index " Cycle so you can see the results that the Recv side should display
'
'    Entering a 0 or CR will terminate the either program at this stage
'
'    The Recv program goes directly into the "Zoo Index ..." section
'
'    If you enter the Zoo Index and Animal Index as the sender shows you SHOULD get the smae display.......
'
'    Well, there lays the problem.
'
'    The recv program can only access Zoo index 1 and it's Animal Indexs 1-5
'
'    NO part of Zoo index 2 is available!
'
'    I don't know why.
'
'    If you can help I thank you in advance
'
'
'
'
'
'   The proper code to correct this would be appreciated
'
'   Thank You

The problem still remains

DIM aZooKeeper(1 TO %MaxZoos) AS GLOBAL ZooType

Code snippet

' I get MapviewAddess

'Assign aZooKeeper(1) this address

aZooKeeper(1)[email protected] ' We have our View Address

' Before the MKMapViewAddress Close
' I do a transfer back

@MkMapViewAddress=aZooKeeper(1)

Is this an incorrect method of doing the transfer back?

It certainly seems so as the receiver gets valid information from only one aZooKeeper array element -> aZooKeeper(x) x=1

Within the sender program the data is perfectly retrievable from all aZooKeer(x) elements that received data (empty for those that are blank)

In code example:

The recv gets the aZooKeeper(1) block correct

but sadly the aZooKeeper(2) block is at default values.

I'm missing a key critical code component!

This darn problem is stressing me out. It's stopping the code completion.

Thank you all

If you can correct the problem I would be grateful.

**Bruce Wood** · 5 Sep 2009, 02:55 PM

I think I have it!!!

Use DIM aZooKeeper(1 TO %MaxZoos) AS GLOBAL ZooType AT MkMapViewAddress

This allows a direct write into the mapfile address space.

Thank you for your help

This site and PowerBasic is incredible.
