	( c-addr u1 -- c-addr u2 )

如果 u1 大於零, u2 等於 u1 減去由 c-addr u1 指定的字元字串在結尾的空白數目. 如果 u1 是零或整個字串都是由零組成的, u2 是零.

	( c-addr u1 -- c-addr u2 )

If u1 is greater than zero, u2 is equal to u1 less the number of spaces at the end of the character string specified by c-addr u1. If u1 is zero or the entire string consists of spaces, u2 is zero.

	( c-addr1 u1 n -- c-addr2 u2 )

用 n 個字元調整在 c-addr1 的字元字串. 結果的字元字串, 由 c-addr2 u2 所指定的, 開始於 c-addr1 加上 n 個字元, 而且是 u1 減去 n 個字元的長度.

參閱: A.17.6.1.0245 /STRING

	( c-addr1 u1 n -- c-addr2 u2 )

Adjust the character string at c-addr1 by n characters. The resulting character string, specified by c-addr2 u2, begins at c-addr1 plus n characters and is u1 minus n characters long.

See: A.17.6.1.0245 /STRING

	( c-addr u -- )

如果 u 大於零, 將開始於 c-addr 的字元位置填入 u 個連續的空白字元之值.

	( c-addr u -- )

If u is greater than zero, store the character value for space in u consecutive character positions beginning at c-addr.

	( c-addr1 c-addr2 u -- )

如果 u 大於零, 從資料空間中的 c-addr1 位址複製 u 個連續的字元到 c-addr2 位址, 從低位址到高位址, 以字元對字元的方式處理.

參閱: A.17.6.1.0910 CMOVE , 17.6.1.0920 CMOVE>

	( c-addr1 c-addr2 u -- )

If u is greater than zero, copy u consecutive characters from the data space starting at c-addr1 to that starting at c-addr2, proceeding character-by-character from lower addresses to higher addresses.

See: A.17.6.1.0910 CMOVE , 17.6.1.0920 CMOVE>

	( c-addr1 c-addr2 u -- )

如果 u 大於零, 從資料空間中的 c-addr1 位址複製 u 個連續的字元到 c-addr2 位址, 從高位址到低位址, 以字元對字元的方式處理.

參閱: 17.6.1.0910 CMOVE , A.17.6.1.0920 CMOVE>

	( c-addr1 c-addr2 u -- )

If u is greater than zero, copy u consecutive characters from the data space starting at c-addr1 to that starting at c-addr2, proceeding character-by-character from higher addresses to lower addresses.

See: 17.6.1.0910 CMOVE , A.17.6.1.0920 CMOVE>

	( c-addr1 u1 c-addr2 u2 -- n )

比較由 c-addr u1 指定的字串到由 c-addr2 u2 指定的字串. 這個開始於給定的位址的字串字元對字元的被比較, 直到到達較短的字串的長度或是找到一個不同為止. 如果兩個字串是相等的, n 是零. 如果兩個字串到較短的字串長度為止是相等的, 且 u1 小於 u2, n 是負一 (-1), 否則是一(1). 如果兩個字串到較短的字串長度為止是不相等的, 且第一個在由 c-addr1 u1 指定的字串中不相等的字元, 與由 c-addr2 u2 指定的字串中對應的字元, 有一個較低的數字值, n 是負一 (-1), 否則是一(1).

參閱: A.17.6.1.0935 COMPARE

	( c-addr1 u1 c-addr2 u2 -- n )

Compare the string specified by c-addr1 u1 to the string specified by c-addr2 u2. The strings are compared, beginning at the given addresses, character by character, up to the length of the shorter string or until a difference is found. If the two strings are identical, n is zero. If the two strings are identical up to the length of the shorter string, n is minus-one (-1) if u1 is less than u2 and one (1) otherwise. If the two strings are not identical up to the length of the shorter string, n is minus-one (-1) if the first non-matching character in the string specified by c-addr1 u1 has a lesser numeric value than the corresponding character in the string specified by c-addr2 u2 and one (1) otherwise.

See: A.17.6.1.0935 COMPARE

	( c-addr1 u1 c-addr2 u2 -- c-addr3 u3 flag )

搜尋由 c-addr1 u1 指定的字串來找由 c-addr2 u2 指定的字串. 如果 flag 是真時, 一個匹配將會在 c-addr3 找到, 而留下的 u3 個字元. 如果 flag 是假時, 表示沒有匹配, 且 c-addr3 是 c-addr1, 且 u3 是 u1.

參閱: A.17.6.1.2191 SEARCH

	( c-addr1 u1 c-addr2 u2 -- c-addr3 u3 flag )

Search the string specified by c-addr1 u1 for the string specified by c-addr2 u2. If flag is true, a match was found at c-addr3 with u3 characters remaining. If flag is false there was no match and c-addr3 is c-addr1 and u3 is u1.

See: A.17.6.1.2191 SEARCH

	解譯: 這個詞的解譯語義是未定義的.

        編譯: ( c-addr1 u -- )

將下列給予的執行時期語義加進目前的定義.

        執行時期:       ( -- c-addr2 u )

傳回一個 c-addr2 u 字串, 它是由 c-addr1 u 在編譯時指定的字元所組成的. 一個程式必須不修改這個被傳回的字串.

參閱: A.17.6.1.2212 SLITERAL

	Interpretation: Interpretation semantics for this word are undefined.

        Compilation: ( c-addr1 u -- )

Append the run-time semantics given below to the current definition.

        Run-time:       ( -- c-addr2 u )

Return c-addr2 u describing a string consisting of the characters specified by c-addr1 u during compilation. A program shall not alter the returned string.
