:The general purpose of structured programming is to organize the flow of control. The general purpose of array operations is to organize the data and provide specialized tools to work with it without needing explicit contol flow for the low-level element-by-element processing. But many, indeed most significant, APL programs still need to manage control flow. Classic APL did this by simulating the structured constructs in most cases. Modern APL generally incorporates versions of structured programming constructs, such as ":IF/:ElseIf/:Else/:EndIf", ":Repeat/:Until", and ":For/:In/:EndFor" and the like.

What does this mean?
:''Nevertheless, some critics attack not the use of a symbolic font, but rather the specific "purely circumstantial" choices that were made during the early implementation of APL, driven by the availability of a special kind of typewriter that would never become mainstream.''
The unmentioned typewriter is the IBM Selectric (why was it unmentioned?). In fact, the whole sentence sounds a lot like innuendo. If this sentence can't be more specific, I'm going to delete it. [[User:Shoaler|Shoaler]] 12:41, 26 May 2005 (UTC)
