S2[]＝[0001，1100，0001，1100，0001，0100]
Afterwards, continue execution in step 202, extract next character " O ", be converted into include expression not this yard---not this yardage group of binary code:
O1[]＝[0010，0010，0010]
In step 203, this yardage group does not convert the control code array into:
O2[]＝[0010，0010，0010]
Wherein, second binary code 0010 converts second photoflash lamp into and opens control code 0010.
In step 204, judge whether there is plural binary code among the O1 [], in this; There are three binary codes in O1 [], so, execution in step 205; Produce the first photoflash lamp closing control sign indicating number 1100 and be inserted between the binary code in the control code array, at this moment:
O2[]＝[0010，1100，0010，1100，0010]
Behind the completing steps 205, execution in step 206 is judged whether character extracts to finish, because the information source character string is " SOS "; Therefore, judged result is " denying ", so execution in step 207 produces the second photoflash lamp closing control sign indicating number 0100; And be inserted into the last of control code array O2 [], make O2 []=[0010,1100,0010; 1100,0010,0100]
Continue execution in step 202, extract next character " S ", be converted into and include not this yardage group of this yard of expression:
S1[]＝[0001，0001，0001]
In step 203, this yardage group does not convert the control code array into:
S2[]＝[0001，0001，0001]
Wherein, first binary code 0001 converts first photoflash lamp into and opens control code 0001.
In step 204, judge whether there is plural binary code among the S1 [], in this; There are three binary codes in S1 [], so, execution in step 205; Produce the first photoflash lamp closing control sign indicating number 1100 and be inserted into the binary code interval in the control code array, at this moment:
S2[]＝[0001，1100，0001，1100，0001]
Behind the completing steps 205, execution in step 206 is judged whether character extracts to finish; Because the information source character string is " SOS ", has extracted last " S ", therefore at present; Judged result is " being ", so execution in step 208 judges in the information source character string " SOS " whether have the word interval information; Its judged result is " denying ", so execution in step 210 produces the 4th photoflash lamp closing control sign indicating number 0000 and is inserted into the last of control code array S2 []:
S2[]＝[0001，1100，0001，1100，0001，0000]
At last, three the control code array S2 [] that obtain more than the merging, O2 [], S2 [], to obtain final control code array:
F2[]＝[0001，1100，0001，1100，0001，0100，0010，1100，0010，1100，0010，0100，0001，1100，0001，1100，0001，0000]
It should be noted that this control code array is a photoflash lamp work control code mentioned above.
