READ -- Reads and executes a file of DEBUG commands.
FORMAT
Read pathname
REQUIRED ARGUMENTS
pathname The pathname of a file containing DEBUG commands.
OPTIONAL ARGUMENTS
None.
DESCRIPTION
A READ command is similar to a Shell script. When you issue the READ command,
DEBUG reads the specified file and executes each line in the file as a DEBUG
command. DEBUG echoes each line of the input file as it reads it.
Note that when you issue DEBUG commands from a command file, DEBUG defers pro-
cessing of GO and STEP commands until all other commands in the file have been
processed. For example, consider the following sample command file:
SET `max_var_len = 66
BREAKPOINT 262
GO
EXAMINE try
When DEBUG processes this file, it defers the execution of the third command,
GO, until last. The EXAMINE command, therefore, will execute before the GO
command.
Command files can themselves contain READ commands.
