My IDL installation (IDL Version 8.5.1, Microsoft Windows (Win32 x86_64 m64)) is suddenly failing to make plots - it gives me a syntax error where there is none. No plot window is created. It did this for a couple of hours yesterday, and then started working normally again. Any ideas as to why this might be happening?
IDL> p=plot(aba_np,aba_ap,symbol='+',linestyle='')
p=plot(aba_np,aba_ap,symbol='+',linestyle='')
^
% Syntax error.
It seems to be failing to load a DLM (XLM?). Sucks as I'm in the middle of a project deadline. Any suggestions appreciated!

I would guess your !path has been compromised.
IDL> print, routine_info('plot', /source, /function)
{ PLOT C:\Program Files\Exelis\IDL85\lib\graphics\plot.pro}

I just tried this, no luck:
IDL> print,routine_info('plot',/source,/function)
% Attempt to call undefined function: 'PLOT'.
% Execution halted at: $MAIN$
I also just uninstalled and reinstalled IDL 8.5.1, still doing the same thing.

Interestingly, calls to contour() work fine.

Are you making any changes to !path manually, in code? You might want to check your syntax that you're using the correct path separator, for example.
If you're making changes in the Workbench Preferences, make sure they're valid and you haven't deleted the default IDL path.
On your platform, check for the presence of plot.pro. It should be installed. On Windows, by default, it's in C:\Program Files\Exelis\IDL85\lib\graphics\plot.pro, for example.
If the file is present, the implication is !path is mangled.
Try this:
IDL> (!path).split(path_sep(/search))
You should see a list of almost 50 directories that begins with entries like this:
C:\Program Files\Exelis\IDL85\lib\bridges
C:\Program Files\Exelis\IDL85\lib\datatypes
C:\Program Files\Exelis\IDL85\lib\dicomex
C:\Program Files\Exelis\IDL85\lib\e3de
C:\Program Files\Exelis\IDL85\lib\enterprise\ese
C:\Program Files\Exelis\IDL85\lib\graphics
C:\Program Files\Exelis\IDL85\lib\hook
C:\Program Files\Exelis\IDL85\lib\imsl
C:\Program Files\Exelis\IDL85\lib\itools\components

plot.pro should be in the $IDL_DIR/lib/graphics directory.
Make sure that you do have plot.pro in this directory, and then make sure this directory is in your !path

Appears to be fixed! I had a mystery variable in my .sav file called 'plot' that must have been the result of an earlier typo. DOH!!! Thanks and sorry for the bonehead post.

Using "compile_opt strictarr" in every routine you write *and* in your
startup file saves a lot of headaches like this.
