Redirection

Under DOS or a Windows Command Prompt, data can be redirected to and from a program. This is normally accomplished by putting redirection symbols on the command line. Here is a list of the redirection symbols supported by EXPL:

>

Writes the output of Device 0 to a file.

<

Reads the input from Device 0 or 1 from a file, instead of from the keyboard.

>>

Appends the output of Device 0 to the end of a file without deleting the information that is already in the file.

|

Reads the output from one command and sends it to Device 0 or 1. Also known as a pipe.

 

EXPL supports these options in two different ways:

 

1. From The IDE. In the IDE, EXPL supports redirection commands specified in the Runtime-Parameters window. The "|" pipe symbol is not supported in this mode.

 

2. From the Command Prompt. EXPL support redirection from the command prompt in Stand-Alone mode programs, . This includes the "|" pipe symbol.
