Re: Parameter lengths and calling from command line

[Alan Campin <alan0307d@xxxxxxxxx>]

You have to pass as '     256 characters ' to tell the command processor to
create a 256a variable. The better option is to just create a command with
a 256a parameters and it does it all. This same behavior will occur in any
other program because it is about the command interpreter.

Think of yourself as the command interpreter. All you get from the command
line is strings of characters. Based on analyzing the strings, you decide
what kind of variables to create and pass to your program. If it sees this,
1233, it says oh must be a number and passes it as a 15.5 number. If it
sees this abc, it says it must be a character string and creates a 32 byte
character field. If it sees 'agc', it says must be a 3 character alpha
field and passes a 3a field. So the only way to get a 256a field is to use
a command or type the quotes and an entire 256a field.
