Valid on Alpha and Integrity server systems only.
Modifies the current attributes for the specified image file.
This command can be used to modify the initial values set by the
OpenVMS Integrity servers Linker for certain image attributes.
NOTE
This command can be executed on an Alpha or Integrity
servers system, but it operates only on Integrity servers
images.
Format
SET IMAGE image-filespec
1 – Parameters
image-filespec
Specifies the name of an OpenVMS Integrity servers image file to
modify. The command overlays the current image file; it does not
create a new version of the image file.
The asterisk (*) and percent sign (%) wildcard characters are
allowed in the file specification if the /RESTORE qualifier is
used. If you omit the file type extension, the default file type
.EXE is applied.
2 – Qualifier
2.1 /FLAGS
/FLAGS=(keyword[,...])
Specifies which image attribute flags to turn on or off. The
original flags are set by the OpenVMS Integrity servers Linker
at image link time. The possible keywords are listed below with
a brief description. For more information about the image link
flags, see the HP OpenVMS Version 8.2 Release Notes.
WARNING
Beware of modifying the flag values unless you are very
knowledgeable about the internals of the image.
Keyword Description
[NO]CALL_DEBUG Call Debugger at startup.
[NO]DBG_IN_DSF Debug records in debug symbol file.
[NO]DBG_IN_IMG Debug records in image file.
[NO]EXE_INIT Image has a pointer to EXE$INITIALIZE.
[NO]IMGSTA Call SYS$IMGSTA.
[NO]INITIALIZE Image has a pointer to LIB$INITIALIZE.
[NO]MAIN Image has a main transfer address.
[NO]MKTHREADS Enable multiple kernel thread use.
[NO]NOP0BUFS No P0 buffers for RMS image I/O.
[NO]P0IMAGE Image is loaded only to P0 space.
[NO]SIGNATURES TIE Signatures are present.
[NO]TBK_IN_DSF Traceback records in debug symbol file.
[NO]TBK_IN_IMG Traceback records in image file.
[NO]UPCALLS User thread upcalls are enabled.
2.2 /LOG
Displays a message to the output device indicating whether the
command successfully modified the image.
2.3 /RESTORE
Restores the original image attributes of the file-that is, the
initial attributes that were set by the OpenVMS Integrity servers
Linker. You cannot specify the /FLAGS or /SUCCESS qualifier when
/RESTORE is used.
2.4 /SUCCESS
Modifies the image link completion code value to SUCCESS. The
run-time behavior of the image remains the same as the original
link.

This example demonstrates how to modify an image to stop the
debugger from being called when the image is initiated. The
image PATCH.EXE was linked with debugging enabled. The SET
IMAGE /FLAGS=NOCALL_DEBUG command allows the debugger to be
bypassed when the image is run.
