$Lstr_Get_Image and $Lstr_Set_Image: Longstring to/from image

Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. There are no OO equivalents for the $Lstr_Get_Image and $Lstr_Set_Image functions.

$Lstr_Get_Image returns the contents of an image as a longstring. $Lstr_Set_Image sets the contents of an image from a longstring.

Syntax

%lstr = $Lstr_Get_Image(image)

%rc = $Lstr_Set_Image(image, value)

Syntax terms

%lstr	A longstring to receive the contents of the image.
%rc	A numeric variable to receive the count of bytes set in the image.
image	A string containing the name of the image to which the function applies. This is a required argument.
value	The longstring from which the image in the `image` argument is to be set.

Usage notes

$Lstr_Get_Image and $Lstr_Set_Image can be useful for maintaining :
- Multiple copies of or versions of an image in a single request
- One or more global copies of an image (using global Longstrings) without using the GTBL space required by the standard GLOBAL IMAGE feature
- Copies of an image associated with a session that survives a logout (using session Longstrings).
