CYDAS UDR Library User’s Guide CYDAS UDR Library Description and Use

Using the Library with DOS BASIC

Each of the supported versions of BASIC consists of two distinct systems. Programs can be loaded into the

BASIC editor and run from within the integrated BASIC environment. Programs can also be compiled by a

command line compiler into stand-alone executable programs that can be run on their own without the help of

the integrated BASIC environment. The CYDAS UDR Library provides the tools for both methods.

BASIC header file

Every BASIC program that uses the CYDAS UDR Library must have a line which includes the BASIC

CYDAS UDR Library header file - CB.BI. The following line should appear near the start of every program,

before the first library call is made.

'$INCLUDE: 'CB.BI'

Using the Library within the integrated BASIC environment

When you start up BASIC, load the "quick library" version of CYDAS UDR Library.

For Quick BASIC, type:

qb /l cbqb

For Professional BASIC, type:

qbx /l

cbpb

For VisualBasic for DOS, type:

vbdos /l cbvb

Using the Library with the BASIC command line compiler

To build stand-alone executable files with the command line compiler, you must link your compiled BASIC

program with the stand-alone version of the CYDAS UDR Library. To do this, you must supply the linker

with the library name. The names of the .lib files are:

 QuickBasic: CBQB.LIB

 Professional Basic: CBPB.LIB

 VisualBasic for DOS: CBVB.LIB

Sample BASIC programs

The sample BASIC programs demonstrate how to call each function in the CYDAS UDR Library. These

programs can be run from within the integrated BASIC environment. They can also be compiled using the

command line compiler with the batch file supplied. The names of the batch files are:

 QuickBasic: MAKEQB.BAT

 Professional BASIC: MAKEPB.BAT

 VisualBasic for DOS: MAKEVB.BAT

Passing arguments to the CYDAS UDR Library

All functions in the library require that arguments be passed to them. The file CB.BI contains the definition of

all the argument types that are passed. In general, there are two classes of arguments: inputs and outputs.
