eval variable=expression

variable=expression

Description

Evaluates the arithmetic or string expression according to the rules of FORTRAN-77 and assigns the result to the variable. The keyword eval can be omitted. FORTRAN-77 function names must be given in lowercase letters.

Examples

eval i = 7
sentence = ’A flexible program!’
j = mod(i,4)**2
l = len(sentence)
show i sentence j l
... Variables:
    i        = 7
    sentence = ’A flexible program!’
    j        = 9
    l        = 19
