The [MKI$](MKI$) function encodes an [INTEGER](INTEGER) numerical value into a 2-byte [ASCII](ASCII) [STRING](STRING) value.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
> result$ = [MKI$](MKI$)(integerVariableOrLiteral%)
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
* integerVariableOrLiteral% is converted to two ASCII characters.
|
||
|
|
* [INTEGER](INTEGER) values can range from -32768 to 32767.
|
||
|
|
* MKI$ string values can be converted back to numerical INTEGER values using [CVI](CVI).
|
||
|
|
* The function takes up less byte space in a file than using the text numerical value when the value is over 2 digits.
|
||
|
|
* When a variable value is used with [PUT](PUT) a numerical value is converted automatically in [RANDOM](RANDOM) and [BINARY](BINARY) files.
|
||
|
|
|
||
|
|
## Example(s)
|
||
|
|
|
||
|
|
How MKI$ creates a two byte string integer value to save file space.

SCREEN 12 '_PRINTSTRING requires a graphic screen mode

|
||
|
|
_PRINTSTRING (222, 252), STR$(number%) + " = " + strng$
|
||
|
|
_PRINTSTRING (252, 300), "MKI$ value = " + Q$ + MKIvalue$ + Q$ 'print ASCII characters
|
||
|
|
LOOP
|

END
|

|
|

```
|

|
|
|
||
|
|
|
||
|
|
> *Explanation:* INPUT in QB64 limits integer entries to 32767 maximum. MOD 256 finds the part of a value from 0 to 255 while the second value is the number of times that 256 can go into the value. [_PRINTSTRING](_PRINTSTRING) can print all of the [ASCII](ASCII) characters.
