GW BASIC 3. 2. 3, IBM Advanced BASIC, IBM Cartridge BASIC and Tandy 1. GW BASIC. Differences with the original languages do arise, and where this is the case they are documented. Please note that Microsofts official documentation for the original languages is rather hit and miss. To avoid making the same errors. The errors in this document are therefore all my own. Please contact me if you encounter them. Functions. Functions can only be used as part of an expression within a statement they may take input values. For example. in PRINT ABS 1 the ABS function is used in an expression within a. PRINT statement in Y SQRX 2 the SQR function. LET statement. Some reference works also use terms such as system variable for functions that do not take. GW BASIC syntax such functions have no parentheses, in contrast to. GeorgeDouros-Symbola-2013.png' alt='Oriya Mn Font' title='Oriya Mn Font' />C family and indeed some modern BASICs. However, this is simply the GW BASIC syntax for functions without inputs. For example, one can do DEF FNA1 PRINT FNA. Oriya Mn Font' title='Oriya Mn Font' />ABSy ABSx. Returns the absolute value of x if x is a number and the. Parameters. ASCval ASCchar. Returns the code point ASCII value for the first character of char. Parameterschar is an expression with. Errorschar has a numeric value Type mismatch. Illegal function call. ATNy ATNx. Returns the inverse tangent of x. Parametersx is a numeric expression that gives. Notes. Unless PC BASIC is run with the double option, this function. ATNx differs in the least significant digit from GW BASIC. Errorsx has a string value Type mismatch. CDBLy CDBLx. Converts the numeric expression x to a double precision value. Errorsx has a string value Type mismatch. CHRchar CHRx. Returns the character with code pointx. Parametersx is a numeric expression in the range 02. Errorsx has a string value Type mismatch. Overflow. x is not in 02. Illegal function call. CINTy CINTx. Converts the numeric expression x to a signed integer. Errorsx has a string value Type mismatch. Overflow. COScosine COSangle. Returns the cosine of angle. Unless PC BASIC is run with the double option. Parametersangle is a numeric expression that. Notes. The return value usually differs from the value returned by GW BASIC in the least significant figure. Errorsangle has a string value Type mismatch. CSNGy CSNGx. Converts the numeric expression x to a single precision value. Errorsx has a string value Type mismatch. CSRLINy CSRLIN. Returns the screen row of the cursor on the active page. Microsoft Visual Studio 2008 Enu Product Family. The return value is in the range 12. This function takes no arguments. CVIy CVIs. Converts a two byte string to a signed integer. Parameterss is a string expression that represents an integer using. Only the first two bytes are used. Errorss has a numeric value Type mismatch. CVSy CVSs. Converts a four byte string to a single precision floating point number. Parameterss is a string expression that represents a single precision. Microsoft Binary Format. Only the first four bytes are used. Errorss has a numeric value Type mismatch. CVDy CVDs. Converts an eight byte string to a double precision floating point number. Parameterss is a string expression that represents a double precision. Microsoft Binary Format. Only the first eight bytes are used. Errorss has a numeric value Type mismatch. DATE functions DATE. Returns the system date as a string in the format mm dd yyyy. This function takes no arguments. ENVIRONvalue ENVIRON x. Returns an environment variable. Parametersx is an expression. If x has a string value, returns the value for the environment variable x or the empty. If x has a numeric value, it must be in 12. Returns the xth entry in. Errorsx is the empty string Illegal function call. Overflow. x is a number not in 12. Illegal function call. EOFisatend EOFfilenum. Returns 1 if file with number filenum has reached end of file 0 otherwise. The file must be open in INPUT or RANDOM mode. EOF0 returns 0. If filenum is open to KYBD, performs a blocking read and returns 1 if. CTRLZ is entered, 0 otherwise. The character entered is then echoed to. Errorsfilenum has a string value Type mismatch. Overflow. filenum is a number not in 02. Illegal function call. Bad file number. The file with number filenum is in OUTPUT or APPEND mode. Bad file mode. ERDEVzero ERDEV. Returns 0. In GW BASIC, returns the value of a device error. This function is not implemented in PC BASIC. This function takes no arguments. ERDEVempty ERDEV. Returns the empty string. In GW BASIC, returns the device name of a device error. This function is not implemented in PC BASIC. This function takes no arguments. ERLerrorline ERL. Returns the line number where the last error was raised. If the error was. If no error has been raised. This function takes no arguments. ERRerrorcode ERR. Returns the number of the last error. If no error has been raised, returns 0. If the last error was a Syntax error raised by a direct statement, returns 0. This function takes no arguments. EXPy EXPx. Returns the exponential of x, i. Parametersx is a number. Notes. Unless PC BASIC is run with the double option, this function returns a single precision. The return value sometimes differs in the least significant digit from GW BASIC. For. large values of x, the difference may be 3 digits. Errorsx has a string value Type mismatch. Overflow. EXTERRzero EXTERRx. Returns 0. Parametersx is a numeric expression in 03. Notes. In GW BASIC, this function returns extended error information from MS DOS. This function is not implemented in PC BASIC. Errorsx has a string value Type mismatch. Overflow. x is not in 03 Illegal function call. FIXwhole FIXnumber. Returns number truncated towards zero. Parametersnumber is a numeric expression. Notes. FIX truncates towards zero it removes the fractional part. By contrast, INT. Errorsnumber is a string expression Type mismatch. FNresult FN name arg0 ,arg1. Evaluates the user defined function previously defined with DEF FNname. Spaces between FN and name are optional. Parametersname is the name of a previously defined function. Errors. No function named name is defined. Undefined user function. The number of parameters differs from the function definition.

The function being called is recursive or mutually recursive. Out of memory. FREfreemem FREx. Returns the available BASIC memory. Parametersx is an expression. If x has a numeric value, it is ignored. If x has a string value, garbage collection is performed. HEXhexrepr HEXx. Returns a string with the hexadecimal representation of x. Parametersx is a.
