postcond

Introduced in the 1977 ANSI M[UMPS] language standard.

This metalanguage symbol represents a condition that specifies whether or not a command or argument is to be executed. Since this syntaxctical element follows the entity on which it operates, it is called a "post-conditional expression".

All commands, except Else, For and If may have a post-conditional expression. The arguments in the Do, Goto and Xecute commands may have post-conditional expressions.

Note: The metalanguage definition of postcond includes the colon that separates the post-conditional expression from the entity on which it operates.
