CROSS-COMPILER (LXB)

Chapter 3

The A-B VBASIC

3–3

Examples:

LXB

In the case above, the operator is prompted for 3 file names.

LXB Prog1

In this case, the file Prog1.BAS is read, and Prog1.LXE is the product. (This

is the fastest compile option.)

LXB Prog1,Prog1,Prog1

File Prog1.BAS is the source, Prog1.LXE and Prog1.LST are generated.

LXB Prog1,Download,PRN

Generate Download.LXE, and send listing directly to the printer (PRN).

LXB Prog1,Startnow,Prog1,Wait

Generate Startnow.LXE and Wait.PGM output files, and Prog1.LST as the

listing file.

A – Source File Specification

The A-B VBASIC compiler requires a plain ASCII text file. By default, the

Visual BASIC editor saves the source text in a compacted format. Be sure to

use the SAVE AS option in Microsoft’s Visual BASIC to save the source as

an ASCII file. LXB cannot recognize the compacted representation.

For a tutorial on BASIC programming, please refer to Microsoft’s “Learning

and Using Microsoft Visual BASIC”, and “Programming in BASIC”, both of

which are supplied with the Application Generator Software (Catalog No.

2708-NAG) and BASIC Language Development Kit Software (Catalog No.

2708-NBD). A list of the STATEMENTS & FUNCTIONS supported by A-B

VBASIC can be found in Appendix C of this manual.
