- INP(<numeric expression>)
- Performs a read from the input port <numeric expression>.
- Returns the value of the input port <numeric expression>.
-
- INT(<numeric expression>)
- Returns the largest integer which is less than or equal to
- <numeric expression>. Examples: INT(-3.5) INT(0) INT(3.14159)
-
- LEFT$(<string expression>,<numeric expression>)
- Returns the leftmost <numeric expression> characters of
- <string expression>. Examples: LEFT$(ANS$,3) LEFT$(A$+B$,N-M)
-
- LEN(<string expression>)
- Returns the length of <string expression>.
- Examples: LEN(A$+B$) LEN(ALPHABET$) LEN("ABC"+STRING$)
-
- * LOC(<variable name>)
- Returns the decimal address of the location in memory
- of the variable's value. Useful for passing addresses
- to routines which are accessed via the CALL function.
- Examples: LOC(ARRAY$(N)) LOC(N) LOC(A$)
-
- LOG(<numeric expression>)
- Returns the natural logarithm (base e) of <numeric expression>.
- Examples: LOG(1) LOG(X^2 +Y/5) LOG(.5*SIN(X+Y))
-
- * MATCH(<string expression>,<string expression>,numeric expression>)
- Returns the position of the first occurance of the first string
- expression in the second string expression, starting with the
- character position indicated by the numeric expression. A
- zero will be returned if no match is found. The following pattern
- matching features are implemented:
-
- 1) A pound sign(#) will match any digit (0-9).
- 2) An exclamation mark (!) will match any upper
- or lower case letter.
- 3) A question mark (?) will match any character.
- Examples: MATCH("DEF","ABCDEFGHIJ",1) (returns 4)
- MATCH(PATTERN$,OBJECT$,START)
-
- MID$(<string expression>,<numeric expression>[,<numeric expression>])
- Without the optional second numeric expression, returns rightmost
- characters of <string expression> starting with the first
- <numeric expression>. With the second numeric expression, returns
- a string whose length is determined by the second numeric expression,
- starting with the character of <string expression> whose position
- is determined by the first numeric expression.
- Examples: MID$(A$,5) MID$(STRING$,POSITION,LENGTH)
