Classes with Statements, Classes as a Program System,ach the individual items of the object. Although by using comprehensive classes and subclasses, we can establish the most complex structures, it will become evident that the concept of classes in SIMULA is even more general and extensive.

lipoatrophy

Co-routines,actual parameters following. As soon as the subprogram is called, the execution of the calling program section is interrupted, and the procedure (perhaps with the actual parameter values) is run through completely. After finishing the subprogram, you branch back to the calling program section, so that the next statements can be executed.

捐助

EXTERNAL-Declaration,RNAL CLASS identifier list of external classes; or EXTERNAL [type] PROCEDURE identifier list of external procedures; By the EXTERNAL-declaration we can fall back upon classes and procedures already existing and include them into the new SIMULA program. The external procedures used may be written in programming languages different from SIMULA.

GOTO-Statement, Loops, and BOOLEAN Variables,pending on values just calculated. This technique includes the repeated passing through parts of the program (“l(fā)oops”). In this chapter, we want to describe different forms of loops made possible by SIMULA. These forms will be pointed out in solving the following problem.

Resign

Input of Data Cards (Standard Input),es to the variables only when the program is actually running. We can achieve this by punching the values for the variables on separate data cards. These cards can be altered from one program course to the next.

保存

Approaching Files,e data blocks are transported to the external medium (the same method is taken conversely, if you want to read the data). The transformation of records into blocks is automatically made by the operating system. Thus, in the SIMULA program, we have to deal with nothing but records.
