Echo(V1.3 in C:) (2.x/3.x internal))
NAME
Echo - Echo a string to the terminal.
SYNOPSIS
Echo [string] NOLINE FIRST LEN
DESCRIPTION
Echo displays its argument to the current output,
this can be the printer, a file or the terminal. Echo is
typically used in scripts, but it can also be used (and
useful) to send escape sequences to things like printers.
2.x/3.x only: You can use echo to output a file to
the environment. This is shown in the example below.
Note that with the added keywords, you MUST use
double quotes to delimit a line to echo under 1.3. Under
2.x/3.x you don't need the quotes ONLY if it appears last
on the command line.
If you want to add a line feed, use the *N character.
But, if you use this option in either 1.3, 2.x, or 3.x
then quotes must be used.
OPTIONS
NOLINE
This suppresses the newline which Echo automatically
adds at the end of its argument. This is useful in that
it allows you to build a single line of text using the
output of two or more commands.
FIRST
This option takes a numeric argument, which indicates
which character position to begin output at. Any
character before FIRST will not be displayed. This is
useful with LEN (see below).
LEN
This option takes a numeric argument, which indicates
how many characters to output. If you also supply a
FIRST argument (see above), character output will begin
with that character, for LEN characters. If LEN is used
without the FIRST keyword, then the final LEN characters
will be displayed.
EXAMPLES
1. To display "Hello World" on the terminal.
Echo "Hello World!"
2. To advance the printer paper, and displays Hello
World! on the printer. Note that you must have set your
escape character to \ for this example to work.
Echo >PRT: "\FHello World!"
3. To display "ello World!".
Echo First 2 "Hello World!"
4. To display "rld!".
Echo Len 4 "Hello World!"
5. To display "World!".
Echo First 7 Len 6 "Hello World!"
6. To print the text file Ram:This.text to your
screen.
Echo Ram:This.text
