PRINTOPREPLY
PRINTOPREPLY
NM and CM callable.
Prints a character string on the system console and solicits a reply.
Syntax
I16 CA I16V I16V
length :=PRINTOPREPLY( message,length,zero ,
CA I16V
reply,maxlength );
Functional Return
length 16-bit signed integer (assigned functional return)
Passes the length of the reply from the system operator. This length
represents a half word count if
maxlength is positive or a byte count if
maxlength is negative.
If
maxlength is zero, then this intrinsic does not solicit a reply.
If an error occurs, the value returned is zero.
The
length parameter can be zero, in which case only the standard
message prefix is written on the system console . If both
length and
maxlength are zero, then CCL (1) is returned.
Parameters
message character array (required)
Passes the characters that are output to the system console. The character
string is limited to 50 characters, additional characters are ignored.
length 16-bit signed integer by value (required)
The length of the output string to be transmitted. If
length is positive, the
length is in half words; if negative, the length is in bytes. Do not specify a
length of >50 bytes.
zero 16-bit signed integer by value (required)
Do not specify this parameter, but maintain parameter position with a
value of 0.
reply character array (required)
Returns the input characters read from the system console.
maxlength 16-bit signed integer by value (required)
The maximum length of the message to be read into the
reply parameter.
If the expected
length is positive, it specifies a half word count; if
