setMemptr procedure

Sets the specified number of bytes from the MEMPTR variable starting at startIndex in a BytesMessage.

Syntax

PROCEDURE setMemptr. DEFINE INPUT PARAMETER memptrVar AS MEMPTR. DEFINE INPUT PARAMETER startIndex AS INTEGER. DEFINE INPUT PARAMETER numBytes AS INTEGER.

Applies to

Message objects

Notes

The first byte is 1.
The setMemptr procedure implicitly calls the clearBody procedure before setting the data and resets after setting the data. Therefore, it can be used whether the message is in a read-only mode or a write-only mode prior to the call.
The call makes a copy of the data. Thus, the memptrVar variable is not modified by the 4GL-JMS implementation and can be modified by the 4GL application after the call without corrupting the message.
