How do I pass a group when starting a new thread

[ChrisH2]

I am trying to pass a group of parameters when starting a new thread. eg: -

Calling Procedure: -

!Start thread, passing 1 parm
SaveThread2 = START(NewProc2,35000,Loc:GroupName)

Procedure Being Called: (NewProc2) -

Prototype: (Group)
Parameter: (MyGroup)


How do I specify the group in NewProc2?

It does not seem to like a Prototype of (Group)

I get the compile error "invalid data type for value parameter"

(*Group) doesnt seem to work either. I get the compile error "No matching prototype available" for the START command.

Has anyone managed to do this?

Hi,

START() can handle only string parameters. Look in the help on the TYPE attribute of groups.

In Global Data :

MyGroupType GROUP,TYPE
B1 byte
S2 string(20)
D3 decimal(10,2)
END

In calling procedure or frame :

PassedGroup GROUP(MyGroupType)
END

Called procedure :

START(MyProcedure, 25000, PassedGroup)

MyProcedure PROCEDURE(STRING PassedGroup)

MyGroup GROUP(MyGroupType)
END

CODE

MyGroup = PassedGroup

...
