3-5 Changing Numeral and Character String Display
This section describes the procedure(s) for changing the contents of the numer-
al and character string memory table entries that are allocated words in the host
and also the procedure for changing the display on the PT by operation at the
host.
For the procedure for displaying the contents of the numeral and character string
memory table entries at the PT, refer to 2-8 Numeral Display (page 140) and 2-9
Character String Display (page 148).
3-5-1 Changing Numeric Values and Character Strings
The PT provides the following methods for changing the contents in the numeral
and character string memory table entries.
• Changing the contents of the allocated word of a numeral memory table
• Changing the contents of the allocated word of a character string memory table
• Copying the contents by operation at the PT status control area
• Pressing a touch switch that has the Copy Setting function
Reference: It is possible to input the data to numeral memory table entries and character
string memory table entries by operation at the PT using the numeral setting
function and the character string setting function.
For details of this operation, refer to 3-7 Input of Numeric Values and Character
Strings (page 327).
Changing the Contents of the Allocated Word of a Numeral Memory Table
By allocating a word for a numeral table entry in the host, it is easy to reflect chan-
ges made at the word in the host to the numeral memory table.
With this method, however, only the contents of the allocated words of memory
table entries being used for display on the current screen of the PT can be read
out. Contents of an allocated word that is not related to the display are not read
out.
