II. Edit / enter data
This option can be used either to enter new data, or to edit an imported data set. The data can be browsed, edited, and then saved. During browsing/editing are shown the original major-element data, sum of the given oxides, and calculated cationic proportions. Displayed are also character fields with details concerning the current analysis (sample name, rock type, locality), and position of the analysis in the data set (such as "2 of 9"). The following options are available:
1-2) Back one, Forward one
Moves one analysis back/ahead. If an attempt to go to a sample number higher then existing data file size is made, a dialogue "Append an analysis?" is entered. Following a positive response, an empty analysis is appended to the end of the current data set.
After invoking this item a cursor appears that can be moved around using the arrow keys and the digits can be overtyped. There is no need to press the decimal point key; similarly, do not press Enter to get to the next row if both decimal digits were entered. Tab key switches between the analysis, sample name, rock type and locality fields. Apart from SiO2 and Al2O3, press Left cursor arrow to input tens. The editing mode is left by pressing Esc. Although the cationic proportions are recalculated as the data are changed, the sum of the analysis is updated just once, when returning to the menu, to speed up the editing.
4) Go to
This option serves for quick browsing of the data set; it is possible to go to:
a) a sequence number in the data set ("Sample no."),
b) a sample name ("ID"),
c) a locality, and
d) a rock type.
Apart from the first option, a case-insensitive substring can be specified. Thus type "Z" to find "Z", "Zero", "zero" or "koz-3". The search will start from the first selected analysis and stop as soon as the first occurrence of the search argument among the selected samples is found. It can be repeated using "Find again". Should no (further) corresponding analysis be found, an error is displayed.
5) Save data
The data can be stored in the following formats:
a) in a dBASE compatible file,
b) in a NewPet *.ROC file,
c) in an ASCII (TAB delimited) file,
d) in a *.CSV file for import into MinPet.
