It is stored coded as 8. Then, the process proceeds to step S4 in FIG. 4, where it is determined whether or not the program input operation has been completed.If the result is YES, the program input is completed.

To explain the program shown in Table 1, in lines 10 and 20, the values of the left margin and tab are set as variables rMJ rTj, respectively. 30 lines to 50
The executable statement on the line is the character string to be printed, and the 60th and 70th lines are the variable "T".

This is an executable statement that stores the tab and left margin position data input in "~1" in the memory area 57 of the RAM 53, and sets the tab and left margin based on the data. Line 90 is the variable 1M.

Along with the numerical value assigned to “T”, [mgns=tabs
This is an executable statement to print the message -J.

Line 100 is an executable statement for sequentially printing each character string shown in lines 30 to 50 based on the tab position data stored in the memory area 57, and lines 110 to 130 are executable statements for sequentially printing each character string shown in lines 30 to 50.
This is an executable statement to print the character string shown in lines 50 to 50 based on the left margin position data stored in the memory area 57.

To execute this program, first operate the rRJ alphabet keys 11 and code key 23, then operate the return key 14, and step S in FIG.
In step S5, the validity of each executable sentence is analyzed by the CPU 50, and the process proceeds to step S6, where it is determined whether each executable sentence has an error. If the result is YES, a tonneau error message #rsYNAXERRORJ is displayed on the display unit 10. If the result is NO, the process advances to step S7, where a display prompting you to input data for setting the margin position and tab position is displayed, and according to the display, operate the numeric keys 12 to set the margin position and tab position. When each is set to "0", for example, the margin position data and tab position data are written to the memory area 57 based on the operation of the CPU 50. Thereafter, in order to print the character string shown in FIG. 6 on the printing paper 3 based on each position data, the printing control means 61 that controls the printing section 51 is controlled by the control means 63, and the character string shown in FIG. 6 is controlled by the control means 63. Based on the program, each character string is printed sequentially starting from the left margin position of the "O" digit.

When performing a printing operation based on separate margin and tab position data according to this program, when prompted to input margin position data and tab position data as the program is executed, press the numeric keys and return key 14. By operating the and inputting the numerical values of rloJ and r2OJ, based on the respective position data, as shown in Fig. 7,
In the second line, character strings are printed sequentially from the 204th tab position, and in the third to fifth lines, three types of character strings are sequentially printed from the left margin position of the 10th column.

As described above, in this embodiment, printing can be automatically performed based on each position data simply by inputting margin position data and tab position data when executing the program.

Table 2 Note that in the above program, the memory area 57
