This metalanguage symbol represents an occurrence of an argument of the Read command. Examples of valid arguments for the Read command appear in an earlier section. The argument of the Read command is either one of a list described below, or an indirection operator (@) followed by an expression that evaluates to a list (separated by commas) of such arguments.
A directly specified Read argument can be a string literal, a format specification, a name of a local variable (possibly subscripted), optionally followed by a colon and a time-out specification, or an asterisk followed by the name of a local variable (possibly subscripted), optionally followed by a colon and a time-out specification.
Modified in the 1995 ANSI M[UMPS] language standard.
A name of a global variable may also occur as an argument of the Read command.
A format specification can also be a reference to a device control function (see the metalanguage symbols mnemonicspace and controlmnemonic.
Introduced in the 1984 ANSI M[UMPS] language standard.
This metalanguage symbol represents the number of characters that will satisfy the current argument of the Read command.
The syntax definition of readcount includes the number sign (#) and the expression that evaluates to a numeric value.
