APPENDIX B CODING EXAMPLES
B.1 Examples of complete control sequences
The general format of a control sequence is:
CSI P1 ... Pn I1 ... Im F
In an 8-bit environment the control function CURSOR FORWARD by one position can be represented in many ways. Examples are:
9/11 3/1 4/3
9/11 3/0 3/1 4/3
9/11 4/3
9/11 3/0 4/3
The second example shows that leading ZEROs (3/0) are not significant. The third and fourth examples use the fact that a default value for CUF is defined and is equal to l.
In a 7-bit enviroment the corresponding examples are:
1/11 5/11 3/1 4/3
1/11 5/11 3/0 3/1 4/3
1/11 5/11 4/3
1/11 5/11 3/0 4/3
In an 8-bit environment SCROLL RIGHT by 28 positions can be represented for instance by:
9/11 3/2 3/8 2/0 4/1
In a 7-bit environment the corresponding representation is:
1/11 5/11 3/2 3/8 2/0 4/1
In an 8-bit environment DEFINE. AREA QUALIFICATION permitting numeric and alphabetic data to be entered into an input area can be represented by:
9/11 3/3 3/11 3/4 6/15
In a 7-bit environment the corresponding representation is:
1/11 5/11 3/3 3/11 3/4 6/15
B.3. Examples of parameter strings

| 4;2 | 3/4 3/11 3/2 | Two parameters having values 4 and 2 respectively. |
| <3 | 3/12 3/3 | A private parameter string. |
| 2; | 3/2 3/11 | Two parameters, the first having the value 2 and the second taking the default value. |
| ;5 | 3/11 3/5 | Two parameters, the first taking the default value and the second having the value 5. |
| 1;;4 | 3/1 3/11 3/11 3/4 | Three parameters, the first having the value 1, the second taking the default value, and the third having the value 4. |
| 0007 | 3/0 3/0 3/0 3/7 | A parameter having the value 7. |
