Matlab programming question on while loop

In the below program the while loop is being executed, but I need to get the changed value of "a" in this line fprintf(dc1, 'SOUR:CURR a') but I am not getting it, could you please help me with this.

It is executing while loop and changing a value from 1 to 3 in increments of 0.5 but in this line fprintf(dc1, 'SOUR:CURR a'); the value of "a" always shows 1. Please advise.

a=1;

while a<=3

fprintf(dc1, 'SOUR:CURR a');

fprintf(dc1, 'SOUR:CURR?');

idn_dc1current = fscanf(dc1)

fprintf(dc1, 'FETC:POW?');

idn_dc1power = fscanf(dc1)

a=a+0.5

end

Thank you and appreciate your help in advance. Hemanth

Maybe you want

fprintf(dc1, 'SOUR:CURR %0.1f', a) ;

hard to say because it's doing exactly what you tell it rather than what you want. But if you want the value of a printed to the file, then do that.
