By calling this library routine you also specify the CRT-STATUS value for the interruption of the ACCEPT statement when the COBOL program receives a message from the embedding HTML page.
Syntax:
CALL "IWC$INIT" USING crtStatus GIVING returnCode |
Parameters:
crtStatus | PIC 9(n) or numeric literal | Specifies the CRT-STATUS value for the interruption of the ACCEPT statement when the COBOL program receives a message from the embedding HTML page |
Return code:
returnCode can be any signed numeric data item.
-1 | Operation failed. Ensure you’re running in WebClient environment |
0 | Operation successful. |
Examples:
Example - initiate the HTML-COBOL communication setting the value 100 as CRT-STATUS value to be returned when the COBOL program receives a message from the HTML page
