Instead, MIN takes two arguments MIN (value1, value2) where value1 and value2 are any numeric scalars and/or arrays. ---------------------------------------------------------------- MIN Type: Verb (function: leaves results on the stack) Use: To obtain the minimum value of numeric scalars (adverbs, subscripted arrays, constants) and/or numeric arrays (adverbs). MIN requires 2 immediate arguments as MIN (value1, value2) where value1 and value2 are any numeric scalars or arrays. Examples: MIN (3.3, 2.3) is 2.3 MIN (-3.3, 2.3) is -3.3 and with LEVS = 1,2,3,4,5,6,7,8,10; I = -6; APARM = 16 MIN (LEVS, I) is -6.0 MIN (LEVS, 43) is 1.0 MIN (LEVS, APARM) is 1.0 One can get away with giving MIN only one argument in a small number of cases, e.g. print MIN(ANTENNAS) will display the minimum value in the array ANTENNAS. If there are other adverbs in the command, MIN will likely pick up one of them to include in the min operation. Thus I = MIN (ANTENNAS) leaves the min of I and ANTENNAS on a stack. In most cases, you are better off using two arguments, e.g. I = MIN (ANTENNAS, ANTENNAS). Adverbs: none. ----------------------------------------------------------------
