Instead, MAX takes two arguments MAX (value1, value2) where value1 and value2 are any numeric scalars and/or arrays. ---------------------------------------------------------------- MAX Type: Verb (function: leaves results on the stack) Use: To obtain the maximum value of numeric scalars (adverbs, subscripted arrays, constants) and/or numeric arrays (adverbs). MAX requires 2 immediate arguments as MAX (value1, value2) where value1 and value2 are any numeric scalars or arrays. Examples: MAX (3.3, 2.3) is 3.3 MAX (-3.3, 2.3) is 3.3 and with LEVS = 1,2,3,4,5,6,7,8,10; I = -6; APARM = 16 MAX (LEVS, I) is 10.0 MAX (LEVS, 43) is 43.0 MAX (LEVS, APARM) is 16.0 One can get away with giving MAX only one argument in a small number of cases, e.g. print MAX(ANTENNAS) will display the maximum value in the array ANTENNAS. If there are other adverbs in the command, MAX will likely pick up one of them to include in the max operation. Thus I = MAX (ANTENNAS) leaves the max of I and ANTENNAS on a stack. In most cases, you are better off using two arguments, e.g. I = MAX (ANTENNAS, ANTENNAS). Adverbs: none. ----------------------------------------------------------------
