B.3 The REVIEW section

By setting the REVIEW environment variable a NEMO program is always put into the REVIEW section just before the start of the actual execution of the program (the end of the initparam(3NEMO) routine). This functionality is quite similar to using the helplevel help=4 (see previous Section).

A NEMO program can also be interrupted, using the quit signal (see signal(2)), into the REVIEW section, although the program must be adapted to get keyword information through getparam(3NEMO) and not through it's own local database, in order for modified keywords to take effect. This does not hold for the system keywords, whose new value is always correctly interpreted by the program.

In the REVIEW section the prompt is ``REVIEW'' and the following commands are understood:

exit, quit, end Exit the program (ungracefully).

stop Gracefully end the program, but first goes through finiparam() (see getparam(3NEMO)) to update the keyword file if the helplevel includes 1.

set [key=[value]] Set a new value for a program keyword (set key=value), where value may also be blank, or display the contents of a program keyword (set key).

show key Show the value of a program keyword.

keys Show the values of all program keywords.

syskeys Show the values of all system keywords.

set syskey[=value] Set a new value for a system keyword set syskey=value or display its current contents set syskey.

time Show the cputime (in minutes) used so far.

!cmd Pass a command cmd to the shell.

go,continue Continue execution of the program.

version Display version of initparam() compiled into program.

?, help Displays all commands and their format.

When the system keyword debug is non-zero, the ``REVIEW'' prompt also includes the process identification number of the process.
