.SH NAME
|
|
pc_pem \- Pascal to EM compiler
|
|
.SH SYNOPSIS
|
|
~em/lib/pc_pem compact errors
|
|
.SH DESCRIPTION
|
|
Pem is a Pascal compiler producing compact EM assembly code.
|
|
The EM machine is described in [1].
|
|
The language Pascal is developed by N. Wirth and is described
|
|
in the "Pascal User Manual and Report" [2].
|
|
The compiler complies as much as possible with the ISO standard proposal [3].
|
|
The language features as processed by this compiler are described in
|
|
the Pascal reference manual [4].
|
|
Normally the compiler is called by means of the user interface program
|
|
\fIack\fP(I).
|
|
.PP
|
|
The first argument is the name of the file on which the produced
|
|
compact EM code is written.
|
|
The file is also used to pass the options to the compiler.
|
|
These options include the -{xxx} flags given to \fIack\fP(I)
|
|
and the size of Pascal objects, like pointers.
|
|
.PP
|
|
The second argument is the name of the error file.
|
|
For each error found by the compiler a record is appended to this file.
|
|
An error record contains several fields like error number, line number,
|
|
column number and error parameter (identifier name or label number etc.).

.SH DIAGNOSTICS
|
|
Compilation errors are written to the error file.
|
|
Positive error numbers are used for irrecoverable errors, negative ones for warnings.
|
|
\fIAck\fP searches the file ~em/etc/pc_errors to find
|
|
the corresponding messages.
