Section 5 Command Descriptions

COUNT
The COUNT command returns the loop count, appended with the serial output
terminator(s), of the last invoked Macro buffer. The number returned is the remaining
number of loops left to execute. It, therefore, is a decrementing count. If Macro 1
requests a COUNT then calls Macro 0, any subsequent COUNT requests made by Macro
1 will return the Macro 0 loop COUNT. The following contents of Macro 1's buffer
should illustrate this…
MACRO 1 Creates Macro Buffer #1
COUNT This will return Macro #1's loop count
DOMACRO 0 This command executes Macro #0
COUNT This will return Macro #0's loop count since it
was the last Macro to be invoked
ENDM01
If Macro #1, in the previous example, was invoked multiple times, each time the
loop counts will be reported as described. This is due to the fact that looping is a re-
invocation of the looped Macro. This command is only valid when contained within a
Macro. Execution outside of a Macro will generate an 'INVALID COMMAND' error.
SYNTAX COUNT
