NAME: cdf0.pro PURPOSE: `cdf0.pro' is used to create a set of structure variables containing the constants used by the CDF library. The structures created and their contents are as follows... CDFconst - General CDF constants. CDFdataType - Data type codes. CDFencoding - Encoding codes. CDFdecoding - Decoding codes. CDFiCode - Informational status codes. CDFwCode - Warning status codes. CDFeCode - Error status codes. CDFiiFnc - Internal Interface functions. CDFiiItem - General Internal Interface items. CDFiiItemA - Internal Interface attribute items. CDFiiItemE - Internal Interface entry items. CDFiiItemR - Internal Interface rVariable items. CDFiiItemZ - Internal Interface zVariable items. These structures contain the same values defined using the `cdf.pro', `cdf1.pro', and `cdf2.pro' batch files. To see the contents of each structure, use the command... IDL> help, /structure, The use of these structures eliminates the problem of too many local variables caused by the use of `cdf.pro', `cdf1.pro', and `cdf2.pro'. This include file is part of the CDF interface provided with the CDF distribution. IDL also provides its own built-in interface to CDFs. If the lengths of these structure names are longer than desired, consider using `cdf0x.pro' instead.
