爲什麼我的批處理腳本將第一行打印爲「Missing Operator」？

所以我決定使用一個子程序來改進當前的程序。我把它放在自己的批處理文件中進行測試，並在不影響整個程序的情況下正常工作，並且我得到了它的工作保存了一件事。出於某種原因，每次運行時，都會打印出「失蹤運算符」作爲其第一行。爲什麼我的批處理腳本將第一行打印爲「Missing Operator」？

注意：我知道它是不正確地執行F到C的轉換。我現在正在解決這個問題。

Subroutine as it is working now.

我不知道這是爲什麼，我需要它不打印任何附加行不僅沒有行詮釋他的計劃，但由於成品節目的每個屏幕都有一組號碼它將在任何時候顯示的行和列。整頁上多出一行，它會切斷應顯示的部分屏幕。

這個子程序（和我使用的測試程序）的代碼是：

@echo off 

:1 
cls 
call :ferDesc 
echo. 
pause 
goto 1
