In this chapter we list some of the useful command line procedures. Note that not all tasks (e.g. plotting) are be performed easily at this level, for which therefore widget routines have been implemented. However, since all data is available at the command level, feel free to analyze it using IDL.
In the following, italic names, e.g. value, have to be replaced
with variable names; if no type is specified in the procedure usage
description, they will be allocated automatically and return the data
requested. If a type is specified, e.g. value_double
, the
variable must be declared and initialized before. Optional arguments are
in square brackets, e.g. status; if several optional arguments
are listed, only one can be selected as such and arguments to the left
then are compulsory! Also remember that you have to enclose character
strings in quotes, unless you stored them in a variable of course.
