170 Pascal 4.0 User’s Guide

Simple Types with the –xl Option

When you pass the -xl option, the Pascal data type real must be paired with

a FORTRAN data type real; the Pascal data type integer must be paired

with a FORTRAN data type, integer*2.

Strings of Characters

The FORTRAN counterpart to the Pascal alfa and string types is a

character string, and the FORTRAN counterpart to the Pascal varying is a

structure. By default, FORTRAN, passes all by reference:

The Pascal procedure,

StrVar.p

type

varstr = varying [25] of char;

procedure strvar_(var a: alfa; var s: string;

var v: varstr);

begin

a := 'abcdefghij';

s := 'abcdefghijklmnopqrtstuvwxyz';

v := 'oyvay'

end; { strvar_ }

The FORTRAN main program,

StrVarmain.f

structure /VarLenStr/

integer nbytes

character a*25

end structure

record /VarLenStr/ vls

character s10*10, s80*80, s25*25

vls.nbytes = 0

Call StrVar( s10, s80, vls )

s25(1:5) = vls.a(1:vls.nbytes)

write (*, 1) s10, s80, s25

1 format("s10='", A, "'",

& / "s80='", A, "'",

& / "s25='", A, "'" )

end
