+% CPSC-KEYWORD-INPUT(7)
+
+# NAME
+
+cpsc-keyword-input - read a value from standard input
+
+# SYNOPSIS
+
+```text
+INPUT variable
+```
+
+# DESCRIPTION
+
+Read into a previously declared INTEGER, REAL, BOOLEAN, CHAR, or STRING
+variable. STRING input reads one whitespace-delimited word. The target must
+be a plain variable; array elements and record/class fields are unsupported,
+unlike the wider INPUT syntax in guide section 5.1.
+
+# EXAMPLE
+
+```text
+DECLARE Name : STRING
+INPUT Name
+OUTPUT Name
+```
