Introduced in the 1977 ANSI M[UMPS] language standard.
This metalanguage symbol represents a segment of source code that is ignored while executing a M[UMPS] program. A comment starts with a semicolon, which must occur in a position where any M[UMPS] command could occur, and ends with the “end of line” marker that designates the end of the line on which the comment occurs. A comment may contain any printable graphic characters.
Note: the ability to use of tabulation characters in comments may be an extension that almost all implementations offer, but it is a non-portable extension.
Introduced in the 1984 ANSI M[UMPS] language standard.
This metalanguage symbol represents the white space between commands. This amount of white space between commands may be one or more space characters.
Approved for addition in a future M[UMPS] language standard:
Spaces may occur at the end of a line.
␣␣␣Set␣X=1␣␣␣Write␣"Hello."␣␣␣
Introduced in the 1990 ANSI M[UMPS] language standard.
This metalanguage symbol represents the general structure of a line of M[UMPS] code. A line of M[UMPS] code consists of zero or more commands and a comment, or just a comment.
Modified in the 1995 ANSI M[UMPS] language standard.
A line of M[UMPS] code consists of zero or more commands and a comment, or just a comment, or zero or more commands, followed by code to be processed by an external code processor.
To be modified in a future M[UMPS] language standard.
Trailing spaces are allowed at the end of a line of M[UMPS] code.
