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 67 lists the keyword constants and integer values you can use.

 

Table 67:

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.
