isalpha

Syntax

isalpha

Comments

isalpha causes a failure to occur if the next non-space character in the data file is not alphabetic.

After this operation, the file continues to be positioned over the character in question; that is, the pointer does not advance.

isalpha can only be used in the header block of a template.

Example

if { isalpha } then 
{
     // act appropriately if it is a letter
} else
{
     // act appropriately if it is not a letter
}
