Memory Tables and Graphs
Reference
There are two methods for accessing character string memory table entries used
for character string display, as follows:
S Direct Specification
S Indirect Specification
Only direct specification can be used as the access method for character string
memory table entries used for character string settings.
Direct specification is a method of specification in which the contents of dis-
played memory table entries are directly correlated with the contents of the al-
located words.
In indirect specification, even if the displayed data is a character string, the dis-
play is correlated with a numeral memory table entry. The contents (numerical
value) of this numeral memory table entry are regarded as a character string
memory table entry number and the contents of the table entry with this num-
ber are displayed.
A combined total 50 of numeral displays and character string displays can be
specified on one screen by using indirect specification.
This specification method is a little complex, but it allows the display to be
changed more easily according to the circumstances. In the example above, if
1 were added to the contents of memory table entry 20 to give 52, the contents
of memory table entry 52 would be displayed instead.
The memory table entries used for display can also be allocated to areas in the
PC, so that the display can also be changed in response to changes in the data
to be displayed (i.e., the contents of character string memory table entry 51 in
the example above).
