This would mean, for example, setting the array size after a button is clicked. If parameter is an array name indexed by `@' or `*', the result is the length members of the array beginning with ${parameter[offset]}. There is no maximum limit on the size of an array, nor any requirement that members be indexed or assigned contiguously. The variables can have long, mnemonic names and can be either character or numeric, although floating point variables are not allowed. Includes convenient programming features, such as built-in arithmetic and a C-like expression syntax. Any variable can become a one-dimensional array by simply referring to it with a subscript. To set an array, use parentheses around the value. # Description: simple array manipulation: create an array, get its length and the # iterate through the array and print out each element # # Input: None # # Output: prints out each element of the array and its position. csh array sizeThe C shell is a Unix shell created by Bill Joy while he was a graduate student at University of The keywords, the use of parentheses and the C shell's built-in expression grammar and support for arrays were all strongly .
