2.11.1.3 Changing memory contents

Memory values can be edited.

In the memory value area or character string area, move the caret to the target memory value and then edit it directly from the keyboard.

When a memory value is edited, the altered portion is displayed in a different color. While in this state, press the [Enter] key and the altered value will be written into the target memory. (Pressing the [Esc] key before you hit the [Enter] key cancels editing.)

However, the character strings that can be entered when changing memory contents are limited to only those that are handleable by the currently specified system of notation. Also, changes in the character string area are only possible when character code in "ASCII" is specified.

You can edit memory values even when the program is in execution. For details, see "2.11.1.4 Displaying and changing memory contents during program execution".

In the case shown below, caution is required when editing the memory values.

Example 1.

When the maximum value of the displayed bit width is exceeded
If, while memory is displayed in decimal 8 bits, you edit the displayed value "105" by entering "3" for "1," then the altered value becomes "127" which is the maximum value.

Example 2.

When "-" is entered in the middle of a numeric value
If, while memory is displayed in signed decimal 16 bits, you edit the displayed value "32768" by entering "-" in the middle of it like "32-68," then numerals "3" and "2" change to spaces and the altered value becomes "-68."

Example 3.

When a space character is entered in the middle of a numeric value
If, while memory is displayed in decimal 16 bits, you edit the displayed value "32767" by entering a space in the middle of it like "32 67," then numerals "3" and "2" change to spaces and the altered value becomes "67."

Example 4.

When the same value is entered
Even when you enter the same value as the current memory value, the specified value is written into memory.
