Editing Stride of an array (section)

===Array cross-section ===
Some languages like [[PL/I]] or [[Fortran]] allow what is known as an ''array cross-section'', which selects certain columns  or rows from a larger array.<ref>{{cite book|last=Hughes|first=Joan K|title=PL/I Structured Programming (second ed.)|year=1979|publisher=John Wiley and Sons|location=New York|isbn=0-471-01908-9|url-access=registration|url=https://archive.org/details/plistructuredpr00hugh}}</ref>{{rp|p.262}}  For example, if a two-dimensional array is declared as
<syntaxhighlight lang="m2">
declare some_array (12,2)fixed;
</syntaxhighlight>
an array of one dimension consisting only of the second column may be referenced as
<syntaxhighlight lang="m2">
some_array(*,2)
</syntaxhighlight>
