The environment for typesetting pseudocode. Everything inside is treated as if it were in math.

Arguments:

1. Name of the algorithm or program.
2. Starting line number (optional). Default starting number is 1. Defined using one the following commands:
   • \NewProgram,
   • \ContinueProgram,
   • \ProgramStartsAtLine.

Use as argument to ppprog to start numbering lines from 1.

Use as argument to ppprog to start numbering lines from where the previous ppprog environment left off. This is meant to facilitiate splitting a program.

Use as argument to ppprog to start numbering lines from an arbitrary number given by argument.

Arguments:

1. Value from which to start numbering lines.

Attaches a label to the current line. The label is as given in the argument, with no prefixes.

Arguments:

1. Name of label.

Attaches a label to the current line. Label if of the form line:algname-labelname, where algname is the name of the algorithm as specified with ppprog and labelname is the argument given.

Arguments:

1. Name of label—last segment.

References a label created with pplab.

Arguments:

1. Name of the algorithm the label is in.
2. Name of label—last segment.

Start a new numbered line.

Start a new unnumbered line. Meant as a way to typeset completely empty lines.

Alias to \ppempty.

Manual indentation.

Add extra space between lines.

Arguments:

1. Amount of vertical space (optional). Default value is 0.1cm.
