A11.2.3 Common Blocks

The common blocks used by the HISCALE IDL software are described below, both to allow the user to access them to use the quantities contained therein, and also to be able to avoid name clashes.

The best way to add a common block to your program is to use the include file from the [.com_include] subdirectory. (For example, to include the common block axis_limits, you should include the line @axis_limits near the start of your program.) This way if the definition of the block is changed your routine will not get out of step---no guarantees are given that new variables will not be added to common blocks, nor that the order will not be changed (however, they will not be removed).

The detailed listing here does not include those common blocks which are private to widget routine pairs (i.e., the creator of a menu and its event handler). Those blocks which all have names ending _wid, their names are listed at the end for completeness.
