#QUERY( section, source )
| #QUERY | Generates source if the named #SUSPEND section has been released. |
| section | The name of the #SUSPEND section to #QUERY. |
| source | The code to generate. |
The #QUERY statement conditionally generates its source based on whether the named #SUSPEND section has been released (either explicitly or implicitly). If the #SUSPEND section has been released then #QUERTY generates its source, without affecting the release of any other nested #SUSPEND section it may be in–it does not create an implict #RELEASE.
Example:
#SUSPEND(Fred) #!Begin suspended generation section named “Fred”
#?1
#SUSPEND #!Begin unnamed suspended generation section
#?2
#QUERY(Fred,'3') #!Generate “3” only if the “Fred” section is released
#?4
#RESUME
5 #!Unconditional generation causes implicit #RELEASE of “Fred”
#RESUME #!End “Fred” section
#!The above code will generate 1, 3, 5 on successive output lines
#!The 2 and 4 don't generate because the unnamed section was not released
