char/2—produce a string containing a single character with a specified numeric internal representation
The char/2 primitive produces a string containing a single character with a specified numeric internal representation.
$STRVAL=char($INTVAL)
char/2 arguments
Argument | Mode | Type | Description |
|---|---|---|---|
$INTVAL | Input | INTEGER | Specifies the integer character code for the single-character string |
$STRVAL | Output | STRING | The single character represented by the integer character code, returned as a string |
Use char/2 to convert the numeric internal representation specified by $INTVAL into a string returned in $STRVAL. The code is implementation-dependent. It currently is the Unicode code point.
Not every numeric code results in a valid character.

$E.msg = char($E.msg);
