Qbasic/QuickBasic Programming

File To Custom Base-64.exe is a Windows standalone executable that allows a user to choose an offset into the ASCII character set from CHR$[32] through CHR$[63] for the Base-64 character set to convert any file into only “typewriter” text that can be copied to the Windows Clipboard and then pasted into Notepad as a text file. The text file produced is exactly 4/3 [1 1/3] larger that the original file. For example, if the offset chosen is at CHR$[32], then the Base-64 character set is from CHR$[32] through CHR$[95]. Another choice useful for encryption is the Random option where a user chooses a locking/unlocking number "key". With this option the Base-64 character set continually shifts during the conversion. Only that chosen number "key" can convert the Base-64 output back into text. So far, this is similar to my earlier program Text To Custom Base-64.exe. However, *the major difference* with this program is that the Base-64 text produced can be copied to the Windows Clipboard and then [instead of pasting into Notepad as a text file] pasted right back into this restarted program - using either a different offset or different Random “key” for saving to an illegible binary file. This binary file is the same size as the original file but it can only be converted back to the original file by doing everything previously done in the reverse order. The attached zip file contains the Windows executable, the source code and a PDF with several screen shots that act as a tutorial.
