System Function CR
Monadic Function
|
||||
| R is a character scalar or vector. | ||||
| Z is a character matrix with as many rows as there are lines in the function (including the header), and as many columns as the longest line (including the header). |
This monadic function behaves the same as described in the Extended APL Standard, except it also displays the canonical representation of an assigned function or operator.
For example,
f←,∘⍋∘⍋∘,
⍴⎕←⎕cr 'f'
,∘⍋∘⍋∘,
1 7
If the assigned function references an unnamed value which is not a simple scalar, the representation shows a marker in that spot.
For example,
f←'abcdefg'∘⎕cr
⎕cr 'f'
…∘⎕cr
f←⎕cr
⎕cr 'f'
f
f 'f'
f
Dyadic Function
|
||||
| R is a character scalar or vector. | ||||
| L is an integer scalar whose value is either 1 or 2. |
If the first character in R is #, then R is assumed to name an internal Magic Function; otherwise R is assumed to name a user-defined function/operator or a directly assigned function (e.g., f←+.×).
If L=2, then Z is a character matrix with as many rows as there are lines in the function (including the header), and as many columns as the longest line (including the header).
If L=1, then Z is either a simple character vector (for directly assigned functions), or a vector of character vectors (for user-defined functions/operators) with as many elements in Z as there are lines in the function (including the header), and each element of Z is a character vector representation of the corresponding line (or header) in the function.
For example,
f←+.×
⍴⎕←2 ⎕cr 'f'
+.×
1 3
⍴⎕←1 ⎕cr 'f'
+.×
3
2 ⎕cr '#MonIota'
Z←#MonIota R
Z←⊃∘.,/⍳¨R
1 ⎕cr '#MonIota'
Z←#MonIota R Z←⊃∘.,/⍳¨R
When this was written, the existing magic functions were named #MonIota, #DydIota, #MonDnShoe, #DydTilde, #MonRank, #DydRank, #Conform, #MonFMT, #Box, and #MonVR.
