Purpose
Define an alternate character to map CHR(0)
Syntax
SET MAPCHAR TO <expN>

Description
The SET MAPCHAR TO command allows the user to define an alternate character to map CHR(0) for output processing. Whenever the CHR(0) function is used, or the ??? "{NULL}" command is used and MAPCHAR is set to a value other than 0, the CHR(0) character is translated into the character specified by the decimal value in <expN>. On output any occurrences of the character specified by <expN> will be translated back to CHR(0). Setting MAPCHAR TO 0 disables character mapping. The default setting is 0.
Example
? chr(64) @ set mapchar to 64 ? chr(0) @
