LEN

The LEN function returns the number of characters including space

characters in a string expression.

Example:

PRINT LEN ("INTERMEC TECHNOLOGIES CORP.") Yields:

MID$

The MID$ function returns a part of a string expression. You can

specify start position and, optionally, the number of characters to be

returned.

Example:

PRINT MID$ ("INTERMEC PRINTER",10,2) Yields:

RIGHT$

The RIGHT$ function returns a certain number of characters from

the right side of a string expression, i.e. from the end. The comple-

mentary instruction is LEFT$.

Example:

PRINT RIGHT$("INTERMEC PRINTER",7) Yields:

PRINTER

SGN

The SGN function returns the sign (1 = positive, -1 = negative or 0

= zero) of a numeric expression.

Example:

PRINT SGN(5-10) Yields:

-1

SPACE$

The SPACE$ function returns a specified number of space charac-

ters and is e.g. useful for creating tables with monospace characters.

Example:

10 FONT "MS050RMN"

20 X%=100 : Y%=300

30 FOR Q%=1 TO 5

40 INPUT "Commodity: ", A$

50 INPUT "Price $:", B$

60 C$=SPACE$(15-LEN(A$))

70 PRPOS X%,Y%

80 PRTXT A$+C$+"$ "+B$

90 Y%=Y%-40

When entering the price in the example

for SPACE$, make sure to use a period

character (.) to indicate the decimal point.
