Memory Occupation
A string variable occupies the memory space by (the number of characters + one) bytes, where
the added one byte is used for the character count. That is, it may occupy 2 to 256 bytes.
If a non-array string variable consisting of 20 characters is declared, for example, it will occupy
21-byte memory space.
[ 2 ] Numeric Variables
• Non-array integer variables
A non-array integer variable should be formatted with an identifier followed by a percent-
age sign (%) as shown below.
Syntax:
identifier%
Example: a%,bcd%
• Array integer variables
An array integer variable should be formatted with an identifier followed by a percentage
sign (%) and a pair of parentheses () as shown below.
Syntax:
identifier%(subscript[,subscript])
Example: e%(10),fg%(2,3),h%(i%,j%)
Where a pair of parentheses indicates an array.
• Non-array real variables
A non-array real variable should be formatted with an identifier only as shown below.
Syntax:
identifier
Example: a,bcd
• Array real variables
An array real variable should be formatted with an identifier followed by a pair of paren-
theses () as shown below.
Syntax:
identifier(subscript[,subscript])
Example: e(10),fg(2,3),h(i%,j%)
Where a pair of parentheses indicates an array.
