NAME

       stilts-tloop - Generates a single-column table from a loop variable

SYNOPSIS

       stilts tloop [ocmd=<cmds>] [omode=out|meta|stats|count|cgi|discard|topcat|samp|tosql|gui]
                    [out=<out-table>] [ofmt=<out-format>] [colname=<value>] [start=<float-value>]
                    [end=<float-value>] [step=<float-value>] [forcefloat=true|false]

DESCRIPTION

       tloop  generates  a  one-column  table  where  the  values  in  the column are effectively
       populated from a for loop (start, end, step). This may be useful as it is, or  it  can  be
       postprocessed with ocmd parameters to add more columns etc.

OPTIONS

ocmd=<cmds>
Specifies processing to be performed on the output table, after all other
processing has taken place. The value of this parameter is one or more of the
filter commands described in SUN/256. If more than one is given, they must be
separated by semicolon characters (";"). This parameter can be repeated multiple
times on the same command line to build up a list of processing steps. The sequence
of commands given in this way defines the processing pipeline which is performed on
the table.

Commands may alteratively be supplied in an external file, by using the indirection
character '@'. Thus a value of "@filename" causes the file filename to be read for
a list of filter commands to execute. The commands in the file may be separated by
newline characters and/or semicolons.

omode=out|meta|stats|count|cgi|discard|topcat|samp|tosql|gui
The mode in which the result table will be output. The default mode is out, which
means that the result will be written as a new table to disk or elsewhere, as
determined by the out and ofmt parameters. However, there are other possibilities,
which correspond to uses to which a table can be put other than outputting it, such
as displaying metadata, calculating statistics, or populating a table in an SQL
database. For some values of this parameter, additional parameters (<mode-args>)
are required to determine the exact behaviour.

Possible values are

* out

* meta

* stats

* count

* cgi

* discard

* topcat

* samp

* tosql

* gui
Use the help=omode flag or see SUN/256 for more information.

out=<out-table>
The location of the output table. This is usually a filename to write to. If it is
equal to the special value "-" (the default) the output table will be written to
standard output.

This parameter must only be given if omode has its default value of "out".

ofmt=<out-format>
Specifies the format in which the output table will be written (one of the ones in
SUN/256 - matching is case-insensitive and you can use just the first few letters).
If it has the special value "(auto)" (the default), then the output filename will
be examined to try to guess what sort of file is required usually by looking at the
extension. If it's not obvious from the filename what output format is intended, an
error will result.

This parameter must only be given if omode has its default value of "out".

colname=<value>
Gives the name of the single column produced by this command.

start=<float-value>
Gives the starting value of the loop variable. This will the the value in the first
row of the table.

end=<float-value>
Gives the value which the loop variable will not exceed. Exceeding is in the
positive or negative sense according to the sense of the step parameter, as usual
for a for-type loop.

step=<float-value>
Amount by which the loop variable will be incremented at each iteration, i.e. each
table row.

forcefloat=true|false
Affects the data type of the loop variable column. If true, the column is always
floating point. If false, and if the other parameters are all of integer type, the
column will be an integer column.

VERSION

       STILTS version 3.1-2-debian

       This is the Debian version of Stilts, which lack the support  of  some  file  formats  and
       network protocols. For differences see
       file:///usr/share/doc/stilts/README.Debian
