terminal width, otherwise the default is the output buffer size.

+.SS COMPILING AND TRACING FORMAT PROGRAMS
+The
+.B \-dump
+switch outputs the complete set of format instructions for the specified
+format program. The
+.B \-trace switch will output each format instruction as it is being
+executed, and show the values of the
+.I num
+and
+.I str
+registers if they have changed from the previous instruction.
+The output buffer is also printed if it has changed from the previous
+instruction.
+.SS FORMAT INSTRUCTIONS
+It should be noted that there is not a one-to-one correspondence between
+format escapes and format instructions; many instructions have side
+effects. Instructions prefixed with
+.RI \*(lq LV \*(rq
+generally return a integer into the
+.I num
+(value) register; instructions prefixed with a
+.RI \*(lq LS \*(rq
+return a string into the
+.I str
+register.
