tableng — Interrogates a function table for length.
kfn -- Table number to be interrogated
tableng returns the length of the specified table. This will be a power of two number in most circumstances. It will not show whether a table has a guardpoint or not. It seems this information is not available in the table's data structure. If the specified table is not found, then 0 will be returned.
Likely to be useful for setting up code for table manipulation operations, such as tablemix and tablecopy.
Here is an example of the tableng opcode. It uses the file tableng.csd.
Example 1074. Example of the tableng opcode.

Its output should include a line like this:
