19. Source for Subprocedure FmtCust

Note

that

NumToChar

is

a

prototyped

procedure,

and

so you might

expe

its prototype inside of FmtCust. You could place the prototype

in Fmt

However,

we placed

it

in

the

main

source section, so that it would

any

subprocedure

we

might

add to

ARRSRPT. This

is

shown later on.

Finally, consider the last subprocedure of this application, NumToChar. N NumToChar does not appear in the ARRSRPT module, that is shown in Figure on page 37. We decided to place NumToChar inside another module calle CVTPROCS. CVTPROCS is a utility module that will contain any conversion pro- cedures that other modules might need to use.

Figure 20 on page 40 shows the source of the module CVTPROCS. Since th prototyped procedure, it needs the prototype to be available. So can be shared, we have placed the prototype into a /COPY file.
