LISTUNREFERENCED or LUR
The C program in Example 5-25 is equivalent to the pTAL program in Example 5-23 on
page 5-33.
If the program in Example 5-25 is compiled and made executable, and the program file
is designated to noft with the option FILE or F on page 5-15, then Example 5-26
shows the result of the LISTUNREFERENCED option—the NMC compiler eliminated
unreferenced prototypes. Compare Example 5-26 to Example 5-30 on page 37, which
shows the result of the LISTUNRESOLVED option.
