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.
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 54 lists the keyword constants and integers you can use.

Table 54: Keyword constants for the CALL-TYPE attribute

Keyword constant	Integer
PROCEDURE-CALL-TYPE	1
FUNCTION-CALL-TYPE	2
GET-ATTR-CALL-TYPE	3
SET-ATTR-CALL-TYPE	4

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.

To set the value of object:attribute to the first parameter set by the SET-PARAMETER( ) method, set CALL-TYPE to SET-ATTR-CALL-TYPE, as in the following fragment:

/* set SESSION:NUMERIC-FORMAT to "european" */ hCall:IN-HANDLE = "session". HCALL:CALL-TYPE = SET-ATTR-CALL-TYPE. hCall:CALL-NAME = "numeric-format". hCall:NUM-PARAMETERS = 1. hCall:SET-PARAMETER( 1, "CHAR", "INPUT", "european"). hCall:INVOKE.

Note: Progress Software Corporation 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 in no way to run triggers for the target field.
