Your assistane would be greatly appreciated

data payment_options;

datalines;
RPP 7 3000
Instant_Payment 7 3000
EFT_On_Us_PAYU 1 1000000
EFT_Off_Us_PAYU 1 1000000
EFT_Pay_to_Cell_PAYU 1 1000000
EFT_On_Us_Bundled 0 1000000

/* Prompt the user for recipient information and amount */
data _null_;
put 'Enter recipient information (cellphone, card, account): ';
input recipient_info $;
put 'Enter amount to send: ';
input amount;
run;

/* Use an IF-ELSE statement to suggest the best payment method */
data suggest_payment;
set payment_options;
if recipient_info = 'cellphone' and amount <= 3000 then output;
else if recipient_info = 'card' and amount <= 1000000 then output;

@Kurt_Bremser pleas help

Have a look at the second data step, the input statement needs either infile or datalines statement to process data.

[Kurt_Bremser · Accepted solution]

This

/* Prompt the user for recipient information and amount */
data _null_;
put 'Enter recipient information (cellphone, card, account): ';
input recipient_info $;
put 'Enter amount to send: ';
input amount;
run;

cannot work. PUT writes to the log or an external file (if assigned with FILE), and INPUT reads from files (INFILE) or DATALINES.

User prompts can be defined in Enterprise Guide and used in EG projects or stored processes.

Depending on the SAS environment the method for "prompting for user" changes.

If you are using a Display Manager environment you want to research the WINDOW and %WINDOW statements, which allows showing a prompt and reading data from a response. Otherwise describe the environment you are working in.

If you aren't going to save the responses in a data set then perhaps the %Window is appropriate to create macro variable values that could be used in your third data step directly.

For SAS EG there are "prompts", SAS even did a video about it:
