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. The following table lists the keyword constants and integer values you can use.

Table 1. 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.
