BUILDER CONVERSION FUNCTIONS
The Builder Library Conversion Functions Consist of Three Very Simple
Yet Handy Functions. Hex2Dec() and Dec2Hex() are Virtually Self-
Explanatory, and I Urge You to Look at Their Samples to See How They
Work. The Use for Asc2Bin() Isn't as Obvious, But is the MOST Useful
Function is This Group.
The Asc2Bin() Function is Priceless, and Here is How I Have Evolved
Using It Most Effectively:
1) Add 1 Field to OPTIONS.DBF for Every Different Printer Escape
Code Your System Will Require. You May Also Put the Data in
the Field At This Time.
2) Remove the Line or Comment Out the Line in the Builder Generated
Source That Closes the OPTIONS.DBF Database. (Or Just Re-Gen
Your Source for Builder to Do This Automatically -- It Will Detect
Fields Added to OPTIONS.DBF!)
3) Add the Neccesary Lines of Code to Save Your New OPTIONS.DBF Fields
to Memory Variables. (Generating Code With Additional OPTIONS.DBF
Fields Will Do this For You)
4) (Optional) Add a Window to Your Program (Under "Utilities") to Edit
the Memory Variables Created in Step 3, and Save Them to OPTIONS.DBF
When Changed. (Very Simple Builder Window With a VERY Simple
Conversion Using the GetEdit() Function)
5) Enter the Command "@ PROW(),PCOL() SAY Asc2Bin(ALLTRIM(YOUR_MEMVAR_HERE))"
as Part of a Printed Report to Send Your Escape Code.
This Method Allows Your Application to Support any Change in Printer
Hardware and it Makes Debugging Printer Escape Codes Easier.
Simple But Effective!
