execute command line
command: EXEC <cmd-line>
Executes the command line given by the string <cmd-line>. Useful if the command lines is stored in a string variable. As an example, let the string "G1 be 'READ QFILE ALL'. Then the statement "G1 will produce an error, because the command line is parsed first and then translated. This will result in a command verb 'READ QFILE ALL', which is not valid. In contrast to this the parameter <cmd-line> of the EXEC command is first translated, then parsed and then the verb and the parameters are translated again. That means the statement EXEC "G1 executes the command 'READ QFILE ALL' as desired.
If <cmd-line> contains an incomplete command line, the possibly following prompts are displayed on the information channel (IC) and all input is read from the main input level (usually level 0).
