<P>
This command causes program input to come from a command script file,
instead of from the keyboard. When the end of file is reached, input will
again be expected to be entered from the keyboard, or from a calling script
file. You may have up to <CODE>20</CODE> nested script files. The 'at'
sign, <CODE>@</CODE>, is equivalent to '<CODE>EXECUTE</CODE>'. Within script
files, it is possible to have labels, <CODE>GOTO</CODE> statements,
<CODE>IF...THEN</CODE> blocks, and <CODE>DO</CODE> loops.</P>
<P>
Numbered parameter zero, that is, <CODE>?0</CODE>,
in a script always is replaced by the file name of the script. Use the
<CODE><a href="../Functions/StringManipulation/string.htm">STRING</a></CODE> function to
convert it to a quote string. For example:</P>
<font color="blue"><PRE>
DISPLAY 'executing script file = '//STRING(?0)</PRE></font>
<P>
If the file name is entered without a filename extension, the current
extension is automatically appended to the filename. The default script
file extension is <CODE>.pcm</CODE>
The <a href="../Characteristics/FileRelated/extension.htm"><CODE>SCRIPTEXTENSION</CODE></a>
characteristic controls the file extension.</P>
<P>
If <CODE>filename</CODE> is a text variable, it is first replaced by its value.</P>
