[Bug-apl] ⎕FIO[49]

[Juergen Sauermann]

Hi,

I have added ⎕FIO[49] to GNU APL in SVN 858.

Z←⎕FIO[49] 'filename' reads the file named filename line by line and stores every line
of the file in one enclosed item of result vector Z , for example (file x has 3 lines):

      ⍪⊃ ⎕FIO[49] 'x'
 Line 1
 Line 2
 Line 3

The end of line character (LF = '\n') character possibly a trailing CR = '\r' character is being removed in the process.

⎕FIO[49] accepts an optional left function argument F which is a monadic conversion function.
The conversion functions F is called with every line read and the result of the function
is then stored in Z. for example:

      ⍪⊃ {'x: ', ⍵} ⎕FIO[49] 'x'
x: Line 1
x: Line 2
x: Line 3
