CVI, CVS, CVD

Syntax

CVI(2-byte string) CVS(4-byte string) CVD(8-byte string)

Versions: Disk

Description

Convert string values to numeric values. Numeric values that are read in from a random disk file must be converted from strings back into numbers. CVI converts a 2-byte string to an integer. CVS converts a 4-byte string to a single precision number. CVD converts an 8-byte string to a double precision number.

Error: Raises "Illegal function call" (error code FC) if the string length is incorrect (not exactly 2, 4, or 8 bytes respectively). See Error Codes for details.

Example

70 FIELD #1, 4 AS N$, 12 AS B$
80 GET #1
90 Y = CVS(N$)
