CALL-TYPE attribute

CALL-TYPE attribute

The type of call, which must be the dynamic version of one of the following:

Invoking an external or internal procedure

Invoking a user-defined function

Invoking a Windows DLL routine or a Unix shared library routine

Getting an attribute

Setting an attribute

Invoking a method

Data type: INTEGER

Access: Readable/Writable

Applies to: Call object handle

You can use a keyword constant or an integer. Table 68 lists the keyword constants and integer values you can use.

Table 68: Keyword constants for the CALL-TYPE attribute

Keyword constant

Integer value

PROCEDURE-CALL-TYPE

1

FUNCTION-CALL-TYPE

2

GET-ATTR-CALL-TYPE

3

SET-ATTR-CALL-TYPE

4

DLL-CALL-TYPE

5

The default is PROCEDURE-CALL-TYPE.

To get the value of an attribute or to invoke a method, set CALL-TYPE to GET-ATTR-CALL-TYPE.

In this example, the SESSION:NUMERIC-FORMAT attribute is assigned, indicated by the CALL-TYPE value of SET-ATTR-CALL-TYPE:
/* Set SESSION:NUMERIC-FORMAT to "european" */ 
ASSIGN 
  hCall:IN-HANDLE      = "session" 
  hCall:CALL-TYPE      = SET-ATTR-CALL-TYPE 
  hCall:CALL-NAME      = "numeric-format" 
  hCall:NUM-PARAMETERS = 1. 
hCall:SET-PARAMETER(1, "CHARACTER", "INPUT", "european"). 
hCall:INVOKE. 
Note: PSC recommends that you do not set the call object's CALL-TYPE attribute to SET-ATTR-CALL-TYPE to set a BUFFER-FIELD object's BUFFER-VALUE attribute, since there is no way to run triggers for the target field.
