Expands macro calls
-
line-num
-
is the number of the program line that contains
either a macro invocation or a macro variable reference to expand.
The MACEXPAND command expands macro invocations
and macro variables. The expansion is displayed in the debugger window. If
the line does not contain a macro invocation or a macro variable reference,
then the MACEXPAND command is ignored.
In this example, the program contains the macro VALAMNT:
%macro valamnt(amount);
if amount <0 or amount >500 then
do;
erroron amount;
_msg_='Amount must be between $0 and $500.';
stop;
end;
else erroroff amount;
%mend valamnt;
Line 33 of the SCL program calls the macro:
%valamnt(amt)
After entering 250 into the Amount
control, enter in the debugger window:
DEBUG> macx 33
The debugger
window displays the following output:
AMOUNT
$T0 = AMOUNT < 0
$T1 = AMOUNT > 500
$T2 = $T0 OR $T1
IF $T2 == 0 THEN #24 ERRORON(AMOUNT)
_MSG_ = 'Amount must be between $0 and $500.'
STOP
JUMP #26
ERROROFF(AMOUNT)
