is there a way to shorten this code:

[dimava]

Randomize
retVal = Int((20 * Rnd) + 1)
If retVal = 1 Then Call fun1
If retVal = 2 Then Call fun2
If retVal = 3 Then Call fun3
If retVal = 4 Then Call fun4
If retVal = 5 Then Call fun5
If retVal = 6 Then Call fun6
If retVal = 7 Then Call fun7
If retVal = 8 Then Call fun8
If retVal = 9 Then Call fun9
If retVal = 10 Then Call fun10
If retVal = 11 Then Call fun11
If retVal = 12 Then Call fun12
If retVal = 13 Then Call fun13
If retVal = 14 Then Call fun14
If retVal = 15 Then Call fun15
If retVal = 16 Then Call fun16
If retVal = 17 Then Call fun17
If retVal = 18 Then Call fun18
If retVal = 19 Then Call fun19
If retVal = 20 Then Call fun20
