Update packages, which are issued between editions, contain additional and replacement pages to be merged into the manual by the customer. The dates on the title page change only when a new edition or a new update is published. No information is incorporated into a reprinting unless it appears as a prior update; the edition does not change when an update is incorporated. The software code printed alongside the date indicates the version level of the software product at the time the manual or update was issued.

First Edition October 1989 HP32715A.00.00 Addition Documentation The following manuals provide information that can help you migrate to HP Business BASIC/XL. HP Business BASIC/XL Reference Manual 32715-90001 HP Business BASIC/XL Programmer's Guide 32715-90002 Link Editor Reference Manual 32650-90030 HP Pascal Programmer's Guide 31502-90002 Switch Programming Guide 32650-90014 Migration Process Guide 30367-90007 Preface This guide describes how to migrate programs from the following languages to HP Business BASIC/XL: * HP Business BASIC/V * BASIC/V * BASIC/260 This guide is intended for experienced BASIC programmers with a good knowledge of the tools used to maintain BASIC programs. This guide has three self-contained sections; one section for each migration path.

In the following example, both the command and the trailing semicolon are required: EXIT; italics Italicized words denote elements that you must replace with an appropriate value. In the following example, you must replace filename with the name of the file you want to close: CLOSE filename [ ] An element inside brackets is optional. Several elements stacked inside brackets means you can select any one or none of these elements. For example: [A] [B] You can select A or B or neither. When brackets are nested, parameters in inner brackets can be specified only if parameters in outer brackets or comma placeholders are specified. For example: [parm1[,parm2[,parm3]]] can be entered as parm1,parm2,parm3 or parm1,,parm3 and so forth. { } When several elements are stacked within braces in a syntax statement, you must select one of those elements. For example: {A} {B} {C} You must select A or B or C. ... A horizontal ellipsis in a syntax statement indicates that a previous statement can be repeated. For example: [,itemname] ... Within examples, vertical and horizontal ellipses show where portions of the example have been omitted. Conventions (continued) Some syntax diagrams in this manual are in the form of "railroad tracks"; alternative paths are indicated by "switches" in the paths. The conventions for the railroad syntax diagrams are: * Items in all uppercase letters represent keywords, predefined symbolic names, and special symbols. These items must be specified exactly as given. * Items in all lowercase letters, with undersocre characters (_) as required, represent items that the user replaces with appropriate entities. * Required items are in ovals or circles. * Items to be replaced by the user are in boxes. * A number n beneath a half circle indicates that the path can be traversed at most n times. * A number n over a half circle indicates that the path must be traversed exactly n times. For example, the syntax diagram for the DO statement looks like this:
NOTE In some diagrams, a number appears in the lower left corner (for example, LG200025_018 in the diagram above). This number is for HP control purposes only and should not be interpreted as part of the diagram or table.
The DO statement syntax on the previous page indicates that a DO statement must begin with the word DO. The word DO is followed by an optional label. If label is used, it can be followed by an optional comma. Next come either the word WHILE, a left parenthesis, a logical expression, and a right parenthesis, or an index, an equal sign, init, a comma, and limit. An optional step follows. If step is used, it must be preceded by a comma. Following are some DO statements that illustrate the syntax. This example uses the DO WHILE path: DO WHILE (i .LE. 10) This example uses label, the optional comma, index, init, limit, and step: DO 10, i = 1, 100, 10 The FORTRAN 77 programs in this manual (programs, program fragments, statements, and so on) use the following conventions: special symbols, keywords, and predefined symbolic names are all in uppercase letters and user-defined symbolic names are in lowercase letters. For example, in the program fragment DO WHILE (count .LE. fibs) WRITE(6,30) count, k i=j j=k k=i + j count = count + 1 END DO the following are predefined symbolic names DO WHILE .LE. WRITE END DO and the following are user-defined symbolic names: count fibs k i j
