REXX Statement Transformation

A REXX statement (actually a clause in REXX terminology) recognized as a host command is transformed before it is passed to the EPI. The EPI sees only the transformed statement, not the original statement that you specified.

The following is the order in which REXX commands are processed:

• Expressions in the statement are evaluated
• The values of REXX variables are substituted for REXX variable names
• Enclosing quotes are removed from literal strings
• Multiple blanks between words are reduced to one blank
