[Lisp-cn] [101] format 常用形式?

神奇的是最基本的 顶层函式:format 就无法使用
先在交互环境中检验:

༄ chez
Chez Scheme Version 9.4
Copyright 1984-2016 Cisco Systems, Inc.

(define _v "v19.1.15.0001")
_v

"v19.1.15.0001"

(format "~a~%" _v)

"v19.1.15.0001\n"
༄ which scheme-script
/usr/local/bin/scheme-script

明确形式后,创建文件 _format.ss:
#! /usr/bin/env scheme-script

(import (rnrs))

(define __version__ "v18.1.14.2201")
(format "by ~a~%" __version__)

一运行就出错:
༄ ./_format.ss
Exception: attempt to reference unbound identifier format at line 6,
char 2 of ./_format.ss

反复看文档: Input/Output Operations
http://cisco.github.io/ChezScheme/csug9.5/io.html#./io:s96

Section 9.13. Formatted Output

procedure: (format format-string obj ...)
procedure: (format #f format-string obj ...)
procedure: (format #t format-string obj ...)
procedure: (format textual-output-port format-string obj ...)
returns: see below
libraries: (chezscheme)

其它形式也都尝试过, 依然是相同的:
... 尝试引用未绑定的标识符格式 <-- 报警
这要怎么想呢?

ps:
(import (rnrs)) 这行注释掉的话,将引发另外的错误:

༄ ./_format.ss
Exception: invalid top-level program import subform (define
__version__ "v18.1.14.2201") at line 4, char 1 of ./_format.ss

这看起来应该是 #! /usr/bin/env scheme-script 引发的对应环境问题....
只是将其替换为
#! /usr/bin/env scheme
运行时将必须追加 chez 或是 scheme 的调用方

我一般直接(import (scheme))

果然...这样引用后

(format "by ~a~%" __version__)
(format #t "by ~a~%" __version__)

后一个有输出, 前一个静默了...

解决 ;-)
多谢
