I understand this - linux is case sensitive:
IDL> .compile sis_bin_mapped_data
% Error opening file. File: sis_bin_mapped_data
IDL> .compile SIS_BIN_MAPPED_DATA
% Error opening file. File: SIS_BIN_MAPPED_DATA
IDL> .compile SIS_bin_mapped_data
% Compiled module: SIS_BIN_MAPPED_DATA.
But there seems to be no way to get it to work at all with this approach:
IDL> resolve_routine,/EITHER,'sis_bin_mapped_data'
% Attempt to call undefined procedure/function: 'SIS_BIN_MAPPED_DATA'.
% Execution halted at: $MAIN$
IDL> resolve_routine,/EITHER,'SIS_BIN_MAPPED_DATA'
% Attempt to call undefined procedure/function: 'SIS_BIN_MAPPED_DATA'.
% Execution halted at: $MAIN$
IDL> resolve_routine,/EITHER,'SIS_bin_mapped_data'
% Attempt to call undefined procedure/function: 'SIS_BIN_MAPPED_DATA'.
% Execution halted at: $MAIN$
SIS_bin_mapped_data.pro is in the current working directory. Seems like the only solution is to rename all files in upper case? Am I missing something?

To be fair to IDL, there are only about two rules
to achieve portability (and maybe a couple more if
you are writing widget programs):
Rule 1: Pay attention to file names. Save files
in lowercase letters and use file routines (e.g.,
FindFile, File_Search, Dialog_Pickfile) to
construct file names.
Rule 2: Save the current device so you can restore
it before you reset it.
thisDevice = !D.Name
Set_Plot, 'PS'
....
Set_Plot, thisDevice
That's about the extent of it. Everything else, to
ITTVIS's credit, just works. :-)
Cheers,
David
