Coerces an expression into a string value. Syntax | |
Formal Declaration | |
Parameters | |
- value
An expression to be coerced. Its type can be anything except BOOL. This function takes the internal bit pattern for value and treats it
as a sequence of ASCII characters. The function value returned is a string
made up of these characters, the length of which is determined by the
natural size of value according to the following table:
Table 8-1 Length of Coerced Strings | Parameter Type | String Length |
|---|
| U16, S16 | 2 | | U32, S32, SPTR | 4 | | S64, LONG class | 8 | | EADDR, SADDR | 12 | | STR | Parameter string length |
Examples | |
$nmdebug > = ascc(%100+%1)
'A'
$nmdebug > wl strlen (ascc(%100+%1))
$2
|
The expression %100+%1 is evaluated and coerced into a string value.
Since the parameter type is effectively U16, the string contains two
characters, a NULL (0) followed by a capital "A".
$nmdebug > var bell strdel(ascc(7),1,1)
$nmdebug > wl bell
<beep>
|
This example builds a single-character string and assigns the result to the
variable named bell. The STRDEL function is used to delete the
leading NULL character, which is returned in the two-character string returned
by the function ASCC. Limitations, Restrictions | |
