Compatibility Issues with PINTofALE
===================================

-vlk (2013-jul-25)


SSWIDL
------

-- Some routines (e.g., UNIQ) have been rewritten in SSW.  Neither starndard IDL,
   nor PINTofALE is compatible with them.  When initale.pro is run, PINTofALE
   forcibly restores compatible compiled binaries of the following programs:
   	PATH_SEP, STRSPLIT, STR_2_ARR, STR_SEP, SYZE, UNIQ
   Further analysis in an SSW environment might fail.


GDL
---

-- Widget based programs (like FITLINES, LINEID, etc) will not work

-- To recompile CHIANTI databases, the CHIANTI routines read_wgfa2.pro
   and read_elvlc.pro (included for convenience in external/) should be
   edited to remove the "$" from the format specification of the reads
   commands.

-- initale cannot be run twice.

-- parts of initale.pro that are designed to bootstrap the location of
   PINTofALE and add it to !PATH fails.
   The environment variable PINTofALE _must_ be set

-- GDL does not have provision to restore compiled binaries (see SSWIDL
   note above)

pre v5 IDL
----------

-- Most programs use "[]" for array indexing and "()" for function calls.
   They will crash in pre-v5 IDL.


IDL v8
------

-- No issues found so far.
