GW-BASIC <strong>User's</strong> Guide CSNG Function Purpose: To convert x to a single-precision number. Syntax: CSNG(x) Comments: x must be a numeric expression (see the CINT and CDBL functions). Examples: 10 A#=975.3421222# 20 PRINT A#; CSNG(A#) RUN 975.3421222 975.3421 file:///C|/Documents%20and%20Settings/Lorenzo/Desktop/GW%20Basic/CSNG.html28/03/2004 21.29.14
GW-BASIC <strong>User's</strong> Guide CHAIN Statement Purpose: To transfer control to the specified program and pass (chain) variables to it from the current program. Syntax: CHAIN[MERGE] filename[,[line][,[ALL][,DELETE range]]] Comments: MERGE overlays the current program with the called program. Note The called program must be an ASCII file (previously saved with the a option) if it is to be merged (see the MERGE command). filename is the name of the program that is called to be chained to. The .BAS extension is assumed unless another is specified. line is a line number or an expression that corresponds to a line number in the called program. It is the starting point for execution of the called program. For example the following begins execution of PROG1.BAS at line 1000: 10 CHAIN "PROG1", 1000 If line is omitted, execution begins at the first line. line is not affected by a RENUM command. However, the line numbers in the specified range are affected by a RENUM command. ALL specifies that every variable in the current program is chained to the called program. For example: 20 CHAIN "PROG1", 1000, ALL If the ALL option is omitted, the current program must contain a COMMON statement to list the variables that are passed. CHAIN executes a RESTORE before it runs the program that it is to be chained to. The READ statement then gets the first item in the DATA statement. Reading will not resume where it left off in the program that is being chained. file:///C|/Documents%20and%20Settings/Lorenzo/Desktop/GW%20Basic/CHAIN.html (1 of 2)28/03/2004 21.29.15
