Help with converting psedco code

program projectx  
String x;
  Boolean f; 
 integer a,z,g; 
 x = readinput; 
 g = length of x;  
z = g minus one; 
 a = zero 
 if g = 1 then 
f = 1
  else  
 f = 1;   
while f=1 and a less than z 

while character at a of x is one of 

[whitespace,comma,semicolon, exclamation_mark, question_mark, or full stop] a++; 

while character at z of x is one of 

[whitespace,comma,semicolon, exclamation_mark, question_mark, or full stop] z--;

 if the toUpperCase of character at a of x is identical to the toUpperCase of character at z of x then a++ and z--;  
  
else f=0; 

if f=0 then print out appropriate message 
 
else 
print out other appropriate message
