<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">CiderPress makes no attempt to verify the correctness of the program. It's possible to import code that can't possibly work. (The same holds true for loading a program from a text file with the "exec" command on an Apple II.)</FONT></P>

<P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">Going the other direction -- converting a BASIC program to a text file -- is easy. Just extract the BAS program to windows, selecting "Configure for easy access in Windows". The conversion is automatic. Note that you must uncheck "Prefer syntax highlighting on BASIC programs" in the <A HREF="t23.htm">file viewer preferences</A>, or it will be saved as a .RTF file to preserve the colored text.</FONT></P>
