Compare Java to MUMPS/Ideas from MUMPS

Introduction

MUMPS has abbreviations for each command. We will have sections in this page for each character of the alphabet. This information is from Ed de Moel's MUMPS by Example web page. Unless otherwise stated, all commands on this page are part of the Standard MUMPS Language and are implemented by all Standard MUMPS vendors. Any commands that are not implemented by all Standard MUMPS vendors are not used by VistA application code.

Commands

Unless otherwise stated, each command may be followed by the colon (:), then a postcondition which is an expression that when evaluated is interpreted as either True (1) or False (0). When the postcondition is interpreted as True, the command is executed with its arguments. When the postcondition is interpreted as False then the command is NOT executed with its arguments and is skipped. The postcondition functions as a "guard" that either allows the command to be executed or not.

Unless otherwise stated, most commands are followed by a space and more information needed to complete the command action. This extra information is a command argument. Most commands that have NO argument will take a default action. The commands that have no extra information are called argumentless commands.
