#?statement
| #? | Defines a single line of source code generated only if #RELEASE commits the conditional source section. |
| statement | A single line of target language code. This may contain template symbols. |
The #? statement defines a single line of source code that is generated only if a #RELEASE statement is encountered. This allows empty unnecessary “boiler-plate” code to be easily removed from the generated source.
A #EMBED that contains source to generate performs an implied #RELEASE. Any generated source output also performs an implied #RELEASE. Therefore, an explicit #RELEASE statement is not always necessary. The #? statement defines an individual conditional source line that does not perform the implied #RELEASE. When a #RESUME is executed without the output to the file being released, any conditional lines of code are un-done back to the matching #SUSPEND.
Example:
ACCEPT #!Unconditional source line
#SUSPEND
#?CASE SELECTED() #!Conditional source line
#FOR(%ScreenField)
#SUSPEND
#?OF %ScreenField #!Conditional source line
#EMBED(%ScreenSetups,'Control selected code'),%ScreenField
#RESUME
#?END #!Conditional source line
#RESUME
#SUSPEND
#?CASE EVENT() #!Conditional source line
#SUSPEND
#?OF EVENT:AlertKey #!Conditional source line
#SUSPEND
#?CASE KEYCODE() #!Conditional source line
#FOR %HotKey
#RELEASE
#?OF %HotKey #!Conditional source line
#EMBED(%HotKeyProc,'Hot Key code'),%HotKey
#ENDFOR
#?END #!Conditional source line
#RESUME
#?END #!Conditional source line
#RESUME
END #!Unconditional source line
