| RDX( ) | Convert ASCII to Radix-40 | 
RDX(ascii$[,ERR=stmtref])
Where:
| ascii$ | Character string containing ASCII data. String expression. | 
| stmtref | Program line number or statement label to which to transfer control. | 
Radix-40 equivalent of given ASCII string.
The RDX( ) function is used to convert data from normal ASCII to Radix-40. Conversion to Radix-40 compresses three characters (any of 0-9, A-Z, ., -, $, or space) into two bytes of data (16 bits).
To convert data back to ASCII, use the inverse function TRX( ).
