Save the current graphic rendition attributes.
Takes a list of codes to save. If no parameters are specified all attributes are saved.
The current setting for each selected attribute is saved to a stack of implementation defined size. The topmost entry of the stack can be restored using restore rendition attributes.
🛈 The stack has a maximum size of 10 entries.
🛈 in version 344 there have been values for
code 12 and 13 which have been "direct color foreground" and "direct color background". These have been removed. Usage of color save/restore in version 344 can lead to glitches.
