SPECX program question

Hello! Quick question -- Is there supposed to be a space between the function being called and the input arguments on the referenced line? Thanks for your help.

ncl/ni/src/lib/nfpfort/specx_dp.f

Line 546 in 83ea393

CALL DDTRNDX (X,NX,IOPT,XINFO(1),XINFO(2),XINFO(3),COEF,IER)

That space is optional, according to fortran standards. In general, the standards allow any number of spaces between elements within a statement.

In practice this becomes a matter of style. Some people program consistently with or without a space between the function name and the parenthesis. Some people don't care and use the space inconsistently. I try to use single space for functions and subroutines, and no space when subscripting variables, so that I can tell them apart.

@Dave-Allured Thanks for clarifying this! Since asking, I continued looking thru scripts and have tested the space or no space, and have realized what you are saying. I like the approach of differentiating between functions/subroutines and scripting variables. I'll go ahead and close -- thanks again!
