7.1 Preparations

We recommend to create an initialisation file (e.g. named which should be called after starting IDL (e.g. @start). This is necessary to define relevant paths of IDL subroutines and to provide the UIO package. Thus, the file should contain the following:

; -- Add user IDL directory to search path --
if strtrim(addpath,2) ne '' then !path=addpath+':'+!path
delvar, addpath
; -- Initialize uio-routines --
uio_init, progrm='by hand'

Alternatively, one might want to set the IDL path variable accordingly like

  export IDL_PATH="+${UIOPATH}/idl"
for example in the .bashrc file.
