SET MAPCHAR

Purpose

Define an alternate character to map CHR(0)

Syntax

SET MAPCHAR TO <expN>

See Also

???, ASC(), CHR()

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)
@
