Limits within a CDF are defined in the appropriate include
files: cdf.h
for C applications
and cdf.inc
for Fortran applications.
The following limits exist:
The maximum number of dimensions that rVariables/zVariables may have.
The maximum number of characters in a variable name.
The maximum number of characters in an attribute name.
The maximum number of characters in a pathname used to specify a CDF.
Most of these limits can be raised. Contact CDF User Support if that becomes necessary.
