Edition Date Software Version --------------------------------------------------------------------------------------- First Edition November 1987 31501A.01.04 Second Edition June 1992 31501A.04.31 . Preface This manual explains how to run FORTRAN 66/V and HP FORTRAN 77/V programs on the MPE/iX operating system and how to covert them to HP FORTRAN 77/iX programs. It is written for experienced FORTRAN programmers. This manual contains the following chapters: Chapter 1 Explains terminology used in this manual. Explains migration to compatibility mode versus migration to native mode. Chapter 2 Discusses the scope of Part I and describes the FORTRAN 66/V to HP FORTRAN 77/V Migration Aid. Chapter 3 Describes the conversions performed by the migration aid. Chapter 4 Describes changes that the migration aid cannot make. Chapter 5 Explains how to run the migration aid and includes a sample migration. Chapter 6 Describes how to modify the migration aid according to your needs. Chapter 7 Describes the scope of Part II Chapter 8 Compares HP FORTRAN 77/iX to HP FORTRAN 77/V, outlining the changed, missing, and new features. Chapter 9 Explains changes to an HP FORTRAN 77/V program that may be required before it can run properly on the MPE/iX system. Chapter 10 Describes data file conversions that allow you to take full advantage of MPE/iX performance improvements. Chapter 11 Summarizes factors affecting migration and offers tips for avoiding migration problems. Additional Documentation This manual does not discuss the MPE/iX operating system in detail. See the appropriate operating system or language manual for complete information about those subjects.

The characters must be entered in the order shown; however, you can enter the characters in either uppercase or lowercase. For example: SHOWJOB can be entered as any of the following: showjob Showjob SHOWJOB It cannot, however, be entered as: shojwob Shojob SHOW_JOB italics In a syntax statement or an example, a word in italics represents a parameter or argument that you must replace with an actual value. In the following example, you must replace filename with the name of the file: RELEASE filename Italics font is also used to emphasize a word or words. punctuation In a syntax statement, punctuation characters (other than brackets, braces, vertical bars, and ellipses) must be entered exactly as shown. In the following example, the parentheses and colon must be entered: (filename):(filename) underlining Within an example that contains interactive dialog, user input and user responses to prompts are indicated by underlining. In the following example, "yes" is the user's response to the prompt: Do you want to continue? >> yes { } In a syntax statement, braces enclose required elements. When several elements are stacked within braces, you must select one. In the following example, you must select either ON or OFF: SETMSG {ON } {OFF} Commands listed in braces are called command lists throughout this manual. Conventions (continued) [ ] In a syntax statement, brackets enclose optional elements. In the following example, ,TEMP can be omitted: PURGE filename[,TEMP] When several elements are stacked within brackets, you can select one or none of the elements. In the following example, you can select devicename or deviceclass or neither. The elements cannot be repeated. SHOWDEV [devicename ] [deviceclass] [...] In a syntax statement, horizontal ellipses enclosed in brackets indicate that you can repeatedly select the element(s) that appear within the immediately preceding pair of brackets or braces. In the example below, you can select itemname zero or more times. Each instance of itemname must be preceded by a comma: [,itemname] [...] In the example below, you only use the comma as a delimiter if itemname is repeated; no comma is used before the first occurrence of itemname: [itemname] [,...] |...| In a syntax statement, horizontal ellipses enclosed in vertical bars indicate that you can select more than one element within the immediately preceding pair of brackets or braces. However, each particular element can only be selected once. In the following example, you must select A, AB, BA or B. The elements cannot be repeated. {A}|...| {B} ...: In an example, horizontal or vertical ellipses indicate where portions of the example have been omitted. In a syntax statement, the space symbol shows a required blank. In the following example, modifier and variable must be separated with a blank: SET [(modifier)] (variable); The symbol indicates a key on the keyboard. For example, RETURN represents the carriage return key. CNTLchar CNTLchar indicates a control character. For example, CNTLY means you press the control key and the Y key simultaneously. Conventions (continued) Comment Explains an operator entry or debug message. > The HP Symbolic Debugger prompt. | Represents "or". ; Separates commands in a command list. base prefixes The prefixes %, #, and $ specify the numerical base of the value that follows: %num specifies an octal number #num specifies a decimal number $num specifies a hexadecimal number If no base is specified, decimal is assumed. Bits (bit:length) When a parameter contains more than one piece of data within its bit field, the different data fields are described in the format Bits (bit:length) bit is the first bit in the field and length is the number of consecutive bits in the field. For example, Bits (13:3) indicates bits 13, 14, and 15:
