ENABLE ATTRIBUTES
FLAG Attribute
FLAG Attribute
You can use the FLAG attribute to set values for flags that can
be referred to in the application skeleton. You can modify the
application skeleton through special commands that ENABLE uses to
test and act upon the value of a user flag. If you modify the
application skeleton by associating user flags with a block of
SCREEN COBOL code, ENABLE uses the value of the FLAG attribute to
determine which blocks of code are to be included or omitted from
the generated SCREEN COBOL program. The syntax of the FLAG
attribute is:
-----------------------------------------------------------------
| |
| FLAG { <flag-number> } <flag-value> |
| { * } |
| |
| <flag-number> |
| |
| is a positive integer from 0 to 99. ENABLE uses the |
| value of <flag-number> to identify a specific user flag |
| in the application skeleton. To determine the |
| appropriate value for <flag-number>, subtract 100 from |
| the value of the user flag number in the skeleton. |
| |
| * |
| |
| indicates that all user flags are set to <flag-value>. |
| |
| <flag-value> |
| |
| is a positive integer from 0 to 255. ENABLE uses |
| <flag-value> to determine which blocks of code are to be |
| generated into or omitted from the portion of the |
| application that refers to the box. |
| |
| The starting value of all FLAG attributes is 0. |
| |
-----------------------------------------------------------------
Consideration
You can specify user flags so that ENABLE includes an entire
block of code in the application, includes only certain lines of
the block of code in the application, or omits the block of code
entirely. Refer to Appendix D for more information about user
flags.
