BASIC code

The basic code, local regulations and this specification carmot be referred to in case of a component failure. 

Note-. In newer versions of BASIC, line numbers are no longer needed. Compare this BASIC code to Excel file ELECTRODE.xls to gain a feeling for the difference in approach necessary to obtain the same result on software platforms geared towards efficient and flexible programming, respectively user convenience. 

Table 5.10. BASIC Code for the Core of Program CORREL...

Some salient features of the apparatus are summarized in this column. The basic code is a three-character alphanumeric, of which the first character is a digit that describes the cell, the second is a letter that indicates whether and how dissolved oxygen was removed, and the third is a digit that identifies the technique of data acquisition. By means of a list of abbreviations, the typical entry "0A0" may be decoded to find that a two-electrode cell was used, that deaeration was accomplished with a stream of inert gas, and that the data were recorded on a pen-and-ink recorder. Inert gases are not identified because that would, In our judgment, consume more space than it would be worth, but they do not include hydrogen because hydrogen is sometimes not inert ... 

We wish to acknowledge discussions with S. Pittel and with Philip Duval, who wrote the basic code for the HB GSB calculation.

The AirClr8 computer program s Basic language code listing is given in Fig. 5.13. This is a Quick Basic or common GW Basic code listing. With the exception of the input-output code, it is also applicable to Visual Basic. 

In keeping with my promise that you can use the same GW Basic code, I have kept all the old code I used in the GW Basic code in the RefFlsh.mak program code. This GW Basic is the same as QuickBasic, IBM Basic, and all the other common Basic languages. This code is installed with the comment line. As you can see, the old code for input-output is more extensive than the code required for VB. I submit, therefore, that VB should be considered an improvement rather than an added burden. 

Note that the original GW Basic or QuickBasic line identification numbers remain in the program. This program is shown in its original form before I installed any VB insertions. The input of txtprt on lines 680 and 710 simply replaced the GW Basic code word Print. Thus the VB text box named txtPrt receives one of the preceding messages if the value of either DPTS or BPTS is less than 1.0.1 confirm that the conversion to VB from GW Basic is really simple. 

To be able writing own kinetics programs it is necessary to get familiarized with the programming language BASIC and particularly with the special BASIC-codes within PHREEQC. 

The BASIC code can be used within the keyword RATES, but also for USER GRAPH, USER PRINT and USER-PUNCH and always occurs between the commands... 

Note that Visual Basic code activated by the command buttons SETUP , SOLVE and CHOOSE POLYNOMIALS provide for concerted calculations from the final worksheet. The code controlling these actions can be viewed using the command sequence ALT/Ell which renders the Visual Basic window visible. 

To examine the macro code that you have just recorded, choose Macro from the Tools menu and Visual Basic Editor from the submenu. Click on the node for the module in the active workbook. This will display the code module sheet containing the Visual Basic code. The macro should look like the example shown in Figure 13-7. 

This macro consists of a single line of code. You ll learn about Visual Basic code in the chapters that follow. 

This is a system of extending the basic EAN code to add on data to the basic code, e.g. bar coded batch code and/or expiry date. In order to achieve this, addition identifiers (AIs) are used to delineate where the additional part of the code begins and ends. This code is much larger than the primary EAN code, e.g. 123 mm long by a minimum of 27 mm high. As it would usually be printed onto cases or trays or tray or case labels, there is more space in which to accommodate the code. Figure 5.19 shows an EAN 128 code.
