Re: Removing blanks from a varning length field.

From your code, the following does you no good because the target
variable is not variable-length.

eval pos1= %scan(' ':encodedExchangeToken);
eval encodedExchangeToken = %subst(encodedExchangeToken:1:POS1-1);

If you change the target variable to variable length then you only
have to do the following -- no scan required (this sets the prefix length
correctly):

eval encodedExchangeToken = %trimr(encodedExchangeToken);

Then the following will work without any additional changes
required (RPG is smart enough to use only the prefix length and ignore the
rest):

cmd = 'echo ' + '''' + encodedExchangeToken + ''' ! openssl +
enc -d -aes-128-ecb -K 363631653237354f494d31554c594c4a +
-nopad -nosalt -base64 -A';
