Figure 11–4.Defining Labels

Figure 11–5.Rewritten Source Code

If there is a label associated with a macro invocation, that label is not used after

expansion and translation. This is because the label is commented out with the

macro invocation. The following source code preprocesses to the intermediate

code as shown:

(a) Source code:

mymac .macro

(b) Intermediate code:

mymac .macro

LABEL is not defined when the code is assembled. Insure that label definitions

do not appear on the same line as the macro invocations. Rewrite the source

code in the example above as follows:

mymac .macro
