Usage Considerations

This directive can appear in the compilation command or anywhere in the source code.

CODE turns the code-listing setting on for subsequent code. CODE has no effect if

NOLIST or SUPPRESS is in effect.

NOCODE turns the code-listing setting off for subsequent code.

PUSHCODE pushes the current code-listing setting onto the directive stack without

changing the current setting.

POPCODE removes the top value from the directive stack and sets the current code-

listing setting to that value.

CODE Listing

The code listing for each procedure follows the local map, if any, for the procedure.

Each line lists an octal address (the offset from the procedure base), followed by eight

words of instructions in octal.

For global variables declared within a named data block, the G+ addresses shown are

relative to the start of the data block and are not the final addresses. At the end of

compilation, BINSERV determines the final G+ addresses for such global variables

and the code locations for items such as PCAL instructions and global read-only

arrays.

After compilation, you can display the final addresses by using Binder and Inspect

commands.

Example of CODE Directive

This compilation command specifies NOCODE to suppress the code listing:

TAL /IN mysrc, OUT $s.#lists/ myobj; NOCODE

COLUMNS Directive

COLUMNS directs the compiler to treat any text beyond the specified column as

comments.

columns-value

is the column beyond which the compiler is to treat text as comments. Specify an

unsigned decimal constant in the range 12 through 132. The default value is 132. If
