Typesetting #tex2html_accent_inline2825# Functions

The following <#1484#>APL<#1484#> function is printed in del-editor style:

A larger font has been selected by inserting the generated code into a 123 environment:

The canonical representation of an <#1485#>APL<#1485#> function is simply a text matrix. Since older <#1486#>APL<#1486#> systems only provide arrays of uniform datatype and rectangular shape, padding of short lines with spaces is performed. In contrast to the del-editor style, the canonical representation is typeset like an <#1487#>APL<#1487#> array with fixed spacing and without line numbering. For the canonical representation of a small typewriter type style was chosen:

<#837#>
#APLcr615#
<#837#>

You notice immediately that we have used the L^ATEX commands 124 and 125 to produce this effect:

In addition to the del-editor representation and the canonical representation of an <#1506#>APL<#1506#> function we provide means for formatting direct definitions of functions, which are supported by only a few <#1507#>APL<#1507#> dialects, e.g. I--<#1508#>APL<#1508#>:

#APLline637#

This direct definition of a function computing Fibonacci numbers is due to [#Iverson87##1###] and has been formatted as follows:

Note, that the <#642#>APLline<#642#> environment allows ligatures within names.
