<p class="PlainText"><a name="Defining"></a>For BS2e, BS2sx, BS2p, BS2pe, and BS2px programs, each editor page can be a separate
|
||
project, or part of a single project. A project is a set of up to eight files that
|
||
should all be downloaded to the BASIC Stamp for a single application. Each of the
|
||
files within the project is downloaded into a separate "program slot". Only the
|
||
BASIC Stamp 2e, 2sx, 2p, 2pe, and 2px modules support multi-file projects.</p>
|
||
<h2>$STAMP Directive for a Multi-File Project</h2>
|
||
<p class="PlainText">For BASIC Stamp projects (consisting of multiple programs), the $STAMP directive
|
||
has an option to specify additional filenames. The syntax below demonstrates this
|
||
form of the $STAMP directive:</p><pre>
|
||
' {$STAMP BS2e, file2, file3, ..., file8}
|
||
</pre>
|
||
<p class="PlainText">Use this form of the $STAMP directive if a project, consisting of multiple files, is desired. This form of the directive must be entered only into the first program (to be downloaded into program slot 0). The file2, file3, etc. items should be the actual name (and optionally the path) of the other files in the project. File2 refers to the program that should be downloaded into program slot 1, file3 is the program that should be downloaded into program slot 2, etc. If no path is given, the filename is given the path of program 0 when loading them into the editor.</p>
|
||
<p class="PlainText">Up to seven filenames can be included, bringing the total to eight files in the project all together. Upon loading, tokenizing, running or viewing program 0 in the Memory Map, the editor will read the $STAMP directive, determine if the indicated files exist, will load them if necessary and change their captions to indicate the project they belong to and their associated program number. After the directive is tokenized properly, and all associated files are labeled properly, tokenizing, running or viewing any program in the Memory Map will result in that program’s entire project being tokenized, downloaded or viewed.</p>
|
||
<p class="PlainText">When program #0 of a multi-file project is opened from diskette, the entire project will be loaded (all referenced files) as well. When a file that is part of a multi-file project is closed, the entire project (all the associated files) will be closed as well.</p>
|
||
<h2>Creating a Multi-File Project</h2>
|
||
<p class="PlainText">To create a project consisting of multiple files, follow these steps:</p>
|
||
<ol>
|
||
<li value="1">Create the first file in the editor and save it (we'll call it Sample.bsx). This will be the program that is downloaded into program slot 0.</li>
|
||
<li value="2">Create at least one other file in the editor and save it also (we'll call it NextProgram.bsx).</li>
|
||
</ol>
|
||
<p class="PlainTextIndent">Note: At this point the editor tabs will be:</p>
|
||
<p class="PlainTextIndent">0:Sample.bsx and 0:NextProgram.bsx.</p>
|
||
<p class="PlainTextIndent">...indicating that there are two unrelated files open "Sample.bsx" and "NextProgram.bsx" and each will be downloaded into program slot 0.</p>
|
||
<ol MadCap:continue="true">
|
||
<li value="3">Go back to the first program and enter or modify the $STAMP directive using the project format. Use "NextProgram" as the File2 argument. For example:</li>
|
||
</ol>
|
||
<p class="PlainTextIndent">' {$STAMP BS2sx, NextProgram.bsx}</p>
|
||
<ol MadCap:continue="true">
|
||
<li value="4">Then tokenize the code by pressing F7 or selecting Run → Check Syntax from the menu.</li>
|
||
</ol>
|
||
<p class="PlainText">At this point, the BASIC Stamp Editor will see the $STAMP directive and realize that this file (Sample.bsx) is the first file in a project and that the second file should be NextProgram.bsx. It will then search for the file on the hard drive (to verify its path is correct), will see that it is already loaded, and then will change the editor tabs to indicate the project relationship. At this point the editor tabs will be:</p>
|
||
<p class="PlainTextIndent">0:Sample.bsx and [Sample] 1:NextProgram.bsx.</p>
|
||
<p class="PlainText">...indicating that there are two related files open; "Sample.bsx" and "NextProgram.bsx". NextProgram.bsx belongs to the "Sample" project and it will be downloaded into program slot 1 and Sample.bsx will be downloaded into program slot 0.</p>
