The conventions used on this page are described in Function call notation conventions.
Summary
- Description
- The IFPROL call (PLACE RECORD ON LIST) places the current record on the specified list.
- Thread type
- multiple cursor IFSTRT, single cursor IFSTRT
- IFCALL function number
- 33
Syntax
IFPROL(RETCODE,LIST_NAME,CURSOR_NAME)
- Compile-only form
- Not available
- Execute-only form
- Not available
Specify the parameters in the syntax order shown above.
Parameter | Description |
---|---|
RETCODE | [O,i,r] The Model 204 return code is the required first parameter. The code is a binary integer value. |
LIST_NAME | [I,c,r] The list name is a required input parameter that specifies the name of the list to be used. If the list does not already exist, Model 204 creates a new list using this name. Specify a character string variable that is the name of a list, existing or new. |
CURSOR_NAME | [I,s,r] The name of the cursor is an input parameter that is available only for use with a multiple cursor IFSTRT thread and is required for specifying the current record to be placed on the list. Specify the cursor name as a short character string (maximum 32 characters), using the name previously assigned to the cursor in a corresponding IFOCUR call. See the description of CURSOR_NAME for the IFOCUR call.
Note: The cursor name is not a valid parameter for use with a single cursor IFSTRT thread. |
Usage notes
Use the IFPROL call to add a record to a list if the record is not already on the list. You may use IFPROL to add records from a sorted set to a list.
The IFPROL call is valid on all types of IFSTRT threads. On a multiple cursor IFSTRT thread, you must specify the cursor whose current record is to be placed on the list. On a single cursor IFSTRT thread, IFPROL places the current record on the list.
Coding example (COBOL)
WORKING-STORAGE SECTION. 01 ARGS-FOR-CALL. 05 RETCODE PIC 9(5) COMP SYNC. 05 LISTNAME PIC X(11) VALUE "NEWEMPLOYS;". . . . PROCEDURE DIVISION. . . . CALL "IFPROL" USING RETCODE, LISTNAME.
In this example, processing is done on a single cursor IFSTRT thread, and the IFPROL call is preceded by IFFIND and IFGET calls (not shown).
