In the general displaying area the
local macro variables and their
values can be seen. In the five
columns the main program and
variables of the four possible
macro levels are listed. A
highlighting bar can be moved
along the variables by means of
arrow keys and ,
while with the help of arrows
and the columns
can be switched over.
Only those variables can be
edited, of which the macro level
is already open. At first only level 0 can be edited, but in case a macro call occurred during
program execution, this enables the editing of a further level. Till a macro level is not open,
editing is unnecessary, for values are given to the variables suitable for the address chain in
time of macro call, while the others are vacated.
Actions of LOCAL MACRO VARIABLES #1–#33 Screen
No action menu can be activated to this screen, by pressing action menu key a blank
action menu is displayed.
It is possible to give value directly to the macro variable by entering a number.
If a vacant value is to be specified, #0 must be entered.
Values can be specified indirectly to the macro variables. This means, that in spite of giving a
value, the variable containing the value must be entered. This way only variables #1–#33,
#100–#199 and #500–#599 can be specified. The local variables represent the values of the
current level.
